Trio15 Classic w/ Voxativ AC-PiFe and PassLabs INT25 Amplifier

Hi Ze’ev,

I picked up my Pass INT-25 last Friday, and then set up over the weekend with my PAP Classics.
Holy smoke!!!  As the expression goes…??.  And I was concerned about a trade off in power for musicality!!!  ???
I need some time to digest this new amp and it’s sonic presentation.  It eliminates some questions I had, however will probably raise some others, and so I thought it would be best to postpone our conversation a little further until I organize my thoughts and questions.
My first impression of the PAP / Pass INT-25 pairing is ???.  NO REGRET.  I feel fortunate that my connection with it was facilitated through your enthusiasm about your experience with your XA.
Thanks Ze’ev.  I’ll be in touch.
————————  a week later  ————————


Until we talk I am simply affirming that your experience with your XA led me to considering the INT, and liking so much what I read about the INT I decided as you know to “go for it”.  I am glad I did!
Wow, what authority they seem to exhibit with the Classic Voxativs!  Any concerns I had about the amp being shy on authority or power with the PAP’s have been dashed.
Presentation is deep and detailed and well sorted….I am seeing that.  The finesse and sonic mass you discuss about the Voxativ PiFe’s are certainly brought out nicely by the amp, and seem to be optimized with the Pass/Voxativ PAP pairing.
Thanks Ze’ev!

Best of RMAF TransRMAF 2015: these speakers (Trio10 MundorfAMT) had it all – superb soundstage, perfect tonality, super open spacious sound that just destroys the walls in the room, all things that great open baffle speakers give you. But, what set this system apart was the laser like focus and lack of “misty” presentation almost every OB speaker has. Plus BASS SLAM. I know you never thought you’d see the words bass slam and Open Baffle ever uttered together. But there it is. I am an OB lover, it’s what I’ve run in my home system for years and years and so I’m a bit jaded about them. But this room raised the bar substantially over every other available OB system I’ve heard. Massive congrats to them for this achievement.”, Jason NotesAudioCircle, Best of RMAF

“Just a beautiful, huge soundstage with real dynamic punch. Even sitting off axis they sound stellar… Man these speakers (Trio10 MundorfAMT) really lock in and ratchet up a LOT. Love it. I think this might actually be best sound in show for me, personally.”, Tyson Notes, AudioCircle, RMAF

59_7PmZ4SL“The PureAudioProject bridges the gap between pure DIY and completely hands-off prebuilt by shipping flat-packed open-baffle speakers which the buyer assembles. This results in providing drivers and crossover components at a level of quality unprecedented even at several multiples of the Trio10 MundorfAMT’s price. PureAudioProject removes the guesswork and provides the opportunity for audiophiles to be involved in creating speakers that out-perform speakers costing much more…”Donald Shaulis,  Complete Review

New Post: ‘The Best Investment in my Life’, Quintet15 w/ Field Coil AC-X in Netherlands

It takes a serious leap of faith on the buyer’s side to place an order for our flagship speakers without having auditioned it, as well as a responsibility challenge for us to collect the payment and supply the speakers.

Reality is that the vast majority of our customers pressed the Buy Now Button without having heard the speakers and here is a feedback we received from a customer that tool this leap of faith and purchased the Quintet15 with Voxativ Field Coil AC-X driver straight ahead !

We express our appreciation for the trust we were given and are happy that this trust worked out to be rewarding for the new owner of this Quintet15.


Email from 6 February 2022:

“For more than 4 decades I have been searching for a way to make music sound believable at home. I grew up with the sound of music instruments so that is my reference. Furthermore my parents took me to the Berliner Philharmoniker and the Wiener Philharmoniker both playing in their own concert halls. I grew up in Amsterdam so I frequently went to the Concertgebouw Orchestra playing  in the Concertgebouw. As well as other famous orchestras, conductors and solo musicians performing in the Concertgebouw. End of my teens I met with a guy whom I still consider my best pal and he was and is totally into old style jazz and playing in a band. So then I visited a lot of jazz performances. Long story to make clear what my references are. I play classical music mostly large symphonic works, but also rock, pop and reggae and I prefer live recordings and to play them at realistic levels. Loud.

I will skip my history of audio equipment, but my last set of loudspeakers were a pair Harbeth 40.2 chosen for their tonal accuracy. I truly believed they would be my last pair. Being an early adopter of digital playback and, as soon as they became available,  ripping techniques I have owned a lot of digital hardware. I ended up with a heavily modified dac with a tube output and capable of playing resolutions up until 96kHz from a dedicated NAS not connected to the network and I thought I was happy. Just enjoying music without the nagging feeling that I needed other equipment. 
For a short term there can be a man’s best friend cialis tadalafil online in also functions to relax arterial pressure. Polyneuropathy is simultaneously damage to peripheral nerves with several different cialis online prices locations. Branded and not best store levitra free just the drug itself have a price. Now, sexual weakness or erectile dysfunction is cialis online india selling here being commonly faced by a numbers of male personalities in the world.
Then I made the mistake accepting a few invitations to listen to classical recording professionals explaining how they work and demonstrating their own work on unaffordable systems. After a few of these sessions the nagging feeling had returned. Especially because they used Merging hardware with a network connection instead of USB. USB was never intended to be used for high quality audio, but it became fashionable and everybody tried to work around its limitations. I had promised myself to only start looking for another digital frontend when it would use a network connection. 

After a long search I fell for a combination of a Grimm MU-1 streamer and a Mola Mola Tambaqui dac and realized my Harbeth 40.2 were not giving me all the goodies so I listened to quite a lot of loudspeakers, but none of them were so much better that the price was justified. To me, that is. Then I remembered PureAudioProject which I have been ‘following’ from the start. Although I did not have the opportunity listen to them I felt I needed to ‘get rid of the box’. 

I contacted Ze’ev and he asked me what I was looking for. I wanted life size orchestra or band and it absolutely had to be tonally correct for strings, voices and piano.  I also made clear I was not interested in another journey to fulfillment in other words an upgrade path. I have always preferred being in Rome over discovering all possible roads leading to it. Ze’ev offered to start with a Voxativ 1.6 and later upgrade if needed, but I ordered a pair of Quintet 15 with the Voxative AC-X field coil drivers, when I realized the difference in the way they are constructed compared to a standard driver and therefore their sonic potential.

After assembling and triple checking everything I switched the system on and then something remarkable happened. Literally within the first few seconds  my love of my life HSP partner exclaimed: “These are going to stay!”. She was right of course. Gone were all the annoying distortions that you have learned to accept as being normal. The soundstage is wide open and accurate and stable. Instruments sound so believable. No edges, no grain. It is so clean. Voices are shockingly real. There is simply nothing annoying. In fact it was shocking and still is.  

A very dear friend of mine is a highly regarded acoustics expert advising at recording sessions and specialized in optimizing recording studios and listening rooms. Last few years he is also a dealer for some carefully selected  really high quality audio equipment. When he heard the set playing he really got emotional. After helping me perfecting the placement he cancelled his next appointment and stayed for over 4 hours instead of 1 hour as was the original plan. He still sends me messages about how amazing the set sounds. 

We are still breaking the speakers in so apparently and according to Ze’ev there is more to come, but this is by far the best music reproduction I have heard. I do realize it is a lot of money. It is for me, but it is the best investment ever. I cannot say anything else. This is what I have been searching for all the time.

The fact that a person with HSP, who normally cannot stand loud voices or loud music is now asking for and enjoying for example live recordings of Pink Floyd or Dead Can Dance or a Bruckner symphony at realistic sound levels tells it all. It is truly amazing. Thank you Ze’ev!”

Don’t mess with 50,000V…

The 8 unfinished baffles came in one box. That box contained only the 8 baffles… no extra samples from the same wood. The samples were to be provided so I could  experiment on the 4 step process of finishing the baffles in the manner in which I wish to have them finished.

The first step is a 50,000 volt “burn” that creates what I would describe as an actual burn pattern into the surface of the wood that is reminiscent of lightning. The pattern and results are different for different species of wood, and thus the need to experiment on the method (voltage, spacing of the contactors, etc.) to achieve the desired results. The carbon from the burn must then be removed from the surface of the wood with steel wool, wire brush and fine sanding. The next step is
applying the correct color of stain or coloured wood oil to achieve the desired color…

Hi, Ze’ev and Rachel,

At 8:30 PM the Grant Fidelity RITA 880 powered up the Q15’s….beautifully!

The horns are awesome right from note one. So much presence… more “live”, more nuance. They surpass the MARTIN Logan Montis already and they are 199.5 hours away from being broken in. Can’t imagine (well, I think I can) how great they will sound then. Even now, the double bass opening up on track 11 (Diana Krall, Love Scenes) tops the ML Montis..(4 x 15 x 2 SHOULD kill the 10” x 2!)… and they do.

I reset the furniture and have 6’2” from speaker centre to speaker centre… it looks good and sounds great. Photos attached. I may abandon the renovation of the old 1940’s radio cabinet… shall ponder on that. I have a different idea.

These horns are GREAT!

Rachel, thank you so much for unequivocally recommending Ze’ev’s speakers. It has been a great experience “building them” and now the real fun starts.

Ze’ev, I was TOTALLY IMPRESSED with how well everything is Engineered, and how perfectly everything fits together. Not one hole out of alignment. I did not sweat even ONCE the entire time I assembled everything. WELL DONE!!!

Actually, Ze’ev, I was reading a blog on Audiogon 2 days ago where a fellow (and his wife) are building a new home, with a 25’ x 35 ‘ dedicated music listening room, with vaulted ceilings from 12’ rising to 16’. He was asking for, and was getting “tons” of replies to his request for suggestions for a HORN speaker system. I read the entire blog(VERY long and at times excruciatingly boring) and no mention from anyone about PAP. I could not resist responding, I’ll send you what I wrote… he responded immediately, asked lots of great questions, and I wrote back a very lengthy reply (I think this is all on the Audiogon blog, so all theses smarty “audiophiles” can read all of it.)

Well, he and his wife looked at your web site thoroughly, watched several U-Tube videos about the Q15 and replied that they are really interested. They like the looks a lot! And the efficiency for tube amplification, small footprint, height is great for their soaring ceilings, and the price is bang-on their budget!

He’s “ willgolf” on Audiogon. He asked me to keep him posted on my assessment of the sound as the break-in period progresses.
You might have another customer soon… several months before the house is completed… so not for a while. I think he’s in the USA… I’ll let you know more when I can.

That’s all for now… time to change the CD. See new photos below. Rachel, send to China!!

I hope my emails are not annoying.

Hi again, Ze’ev,
I just posted this comment on Audiogon to the question someone asked, “What opinions are there with respect to any speakers that are considered to be “giant killers” to some of the best most expensive speakers pt there?”
I took some liberties in making assumptions… I hope I did mot say anything that you find my mid representative.
Ken .

Very few, if any, contributors to this excellent question are providing REASONS why a specific speaker is a superior VALUE for the price…IE, “a true “giant killer”.
Here are the money reasons why this relatively little known brand IS:
1) they are shipped in a DIY “kit” in between about 4 and 7 packages depending on the model chosen (from 4 different countries, each of which make the specifically selected components)
2) Shipping costs are therefore substantially more cost effective. It’s cheaper to ship 7 “little” boxes that 2 gigantic ones that require a pallet and special handling and delivery requirements.
3) they are shipped from the individual manufacturers of each of the components DIRECTLY to you…not to a retail dealership, who needs to pay costs for retail premises, staff, commissions, insurance, electricity. heating and air conditioning, business taxes, inventory, etc., etc. This is a HUGE cost of buying at a retailer! Ask yourself, what’s the mark- up (wholesale to retail) by the dealer and WHY does that have to be that way? Well, it does have to be that way or the retailer will nor be in business.
4) YOU assemble the components. It’s simple, if you know one end of a screwdriver from the other. It took me 5 hours. Therefore, I paid no one a dime for the cost to have someone else do that.
5) the reason these speakers are so “under the radar”, is because the “manufacturer of the speaker systems”, does not spend vast sums of money advertising in trade magazines. Huge savings in his overhead, making it possible for him to pass saving on to the purchasers while still achieving his required profit. Every speaker company requires profit!
6) So how does this speaker system “manufacturer” sell? Trade shows, and word of mouth…personal referrals, and from the most extensive and informative Web site I have ever seen… smart marketing in the money sense. AND, number one, VALUE FOR OUTSTANDING SOUND!!! Without achieving that, you are dead in the water. (Well, maybe not. It’s surprising what people will buy with such little due diligence.)

As an additional bonus, you can customize them with your choice of several different (nearly) full range driver choices, including Voxative models, Tang Bang, Horns, etc. Etc.
Additionally, those drivers are exchangeable/upgradable in the future with the easy modification to the crossovers (which you also assembled… with nothing more than that same screwdriver. Therefore, you can upgrade with out selling 80 % of your speaker system.

SOUND: the model I selected for a rather large listening room, (PAP Quintet Horn 1 Neo 15) with 4 15” neodymium magnet (very fast) woofers, (in each speaker)  NO subs required!!!! …. exceeded IN EVERY RESPECT, the excellent sound of the Martin Logan Montis that I had enjoyed for the past 5+ years.  And I mean EVERY respect! So go through the 50 or so words we use to describe sound from speakers, and check off every one of them.

This brand offers several models, with numerous choices for “centre” drivers to customize the sound for your preference.

One  last comment. The model I chose, besides being able to fill my large room, are about 96 dB efficient. I can blow myself out of my chair with my 8 watts, but apparently, 4.5 watts will do the same. That’s what  they are demoed with at the trade shows.  You can save a LOT of $$$$ on not needing huge, expensive power amplification!

At  double the price of new, these would likely rival many of the “best” out there, and simply blow away the vast majority!

You want to know WHY a speaker is a “giant killer…. now you know.

Do yourself a favour, if you know one end of a screwdriver from the other, (and can use an Allen wrench) and check this brand out  before you buy either new or used.

I have no vested interests… just sharing some FACTS to consider, prompted by the question that was asked.  I am extremely grateful to the person that l learned about this little known brand from, thank you again, Rachel!

PS: AI wish I could post a photo of my pair… I customized the open baffle German white oak
in which the 15’s are mounted and these are now( I guarantee) one if a kind, in appearance. Ken
