I've built the Aleph J and F6 prior to the M2x. Each time, the boards were top quality. The build guides and member assistance from the forum are just fantastic. The M2x is my favorite of the 3, so far having only tried the Ishikawa input stage. In fact, it's the best sounding amp I've ever had.
Great boards. I made a mistake in the assembly. Removal and rework of the part caused absolutly no damage to the board. Many cheap boards would not have fared so well.

My M2X is still in progress. So I can`t tell you how the different input boards affect the sound.
PCBs are very good quality (as always!). Delivery was very fast. But customs take their time
(it was around christmas time!).
I am very pleased with the possibilities to change the input boards. Nice toy to play with.
Unusually I got the EDCOR-transformers first, then the pcbs, and still waiting for some
other parts.
Thanks to
Nelson Pass, Mark Johnson, 6L6 and all other involved persons...

Arrived in perfect order. Boards well
Made. Have not had a chance to start work as yet.
These boards are fine by themselves and represent a rare opportunity for DIYers: take advantage of a superb Pass design that has been augmented by Johnson's fine daughterboard concept. Great stuff all around.
The problems anyone will have are related to the difficulty of obtaining certain parts. The trimpot is currently backordered everywhere and a substitute must be tried. Fortunately, Edcor is making the transformers available and this company is pleasant to deal with.
What is needed is the flexibility to order one or another board individually. Problems can occur and when a board is ruined, an entire set must be purchased just to replenish that one ruined board.
Those of us that have taken advantage of the M2x thread, with OP Johnson, know how helpful this crew is. An exceptional group of fine professionals helping folks they don't even know -- KUDOs, DIYers!
Boards are standard DIYAudiostore boards, they are excellent quality. The amp is exceptional! It is one of the best sounding i have had the pleasure of listening to in my room with my system.
Very nice PCB and good service
Exceptional amplifier in every regard. I especially like the ability to swap front ends. This allowed me to take my system to the next level.
This is my first Pass amp project. The amp boards are nearly ready to install. I’m very pleased with the board quality and value. The ability to use different buffer boards at the input is brilliant. Although I have poked around on diyaudio for many years, I resisted building anything, believing that low power would be inadequate. My mistake to wait so long.
I managed to ruin some traces on an M2 build. As I was researching as to if I could resurrect the build, when I happened upon the M2x thread, and jumped at the chance. The boards are wonderful of course, and they promptly arrived. I built a pair of mono-block amplifiers with boutique parts, and a set of Fairchild FQA mosfets. I have completed the Mountain View and Ishikawa boards so far, the the other 3 are in process.
These amps sing, and easily are the best I have built. Highly recommended.
Fast delivery. Excelent quality. Me :)
Hello DIY ers. Ordered the M2X PCB set. Arrived quickly. Good quality boards, designators clearly marked, Layout design is good. The various driver boards are fun to experiment with. So far I haven't been able to hear any significant differences in the various driver boards. I will do more critical listening after I run the unit a while and gain confidence before connecting to my best speakers. I added Mill-Max pin and socket sets for the add on boards. Some special attention required but super convenient. The amp sounds very good, and I am critical on audio quality. I have observed many reports describing sound and believe words fall short in expressing the quality of sound. This amp provides clarity. What I notice is instruments sound like they are 6-8 feet in front of me with other amps. They sound like they are 2-3 feet in front of me with this amp. Multiple instruments maintain their identities better with this amp. Still digging in to various recordings and finding enjoyment in the pure sound. Thanks to the folks who worked to provide the DIY kits. A big thanks to Mr. Pass for sharing the designs of incredibly practical circuits that shine with audio quality.
Great Service Very nice boards
My M2x boards were fast delivered after Blue Friday order.
Thanks to that offer i came up close to original price with customs fees.
Boards have excellent quality construction good to solder with bit
experience and patience.
Currently i am collecting needed parts for daughter cards, so it will
need bit more time to go for enjoying a Papa masterpiece construction.
Many thanks for great work of all involved who is working in diyAudio store
for our DIY hobby, to make possible great enjoyment with superb amps.
Top quality PCB's and very nice looking too. Very easy to stuff and many options if you happen to choose a part similar but different footprint.
Just finished M2x and mountainview buffer boards. Very organic and musical amp. I like it a lot. Highly Recommended.
As usual, high quality boards from DIY Audio, well packaged fast delivery
M2x pcb good make and reliable store
Thanks for the really nice M2X and all the input pcbs (I have checked). I paid for the USPS Priority Mail shipping service and as promised they were delivered to my door in the UK in six days. Previously I have paid for the standard shipping and delivery has taken weeks (mainly being held in the customs shed at Heathrow Airport). I am looking forward building the amps as this will be my first exposure to N Pass stuff. My wife tells me that I have other stuff to finish first but the choice of five input boards is pure adrenaline to the tinkerer in me. Can I resist?
I read about the M2X power amplifier online, and decided I had to build one. I am still gathering parts, but can say I really appreciate the very evident high quality of the PCB boards. I would note that those input stage "daughterboards" are quite small, and the Austin daughterboard has so much going on that it is DEFINITELY best left for experienced DIY'ers with nimble fingers... or your friendly neighbourhood electronics repair tech, as I plan to do.
One of the things I found most interesting about the MZX amplifier design was the ability to try five different input boards, with each have their own unique signature sound. I am going to start with the Ishikawa daughterboards, as they most closely match up with Nelson Pass's original M2 power amplifier design. These are very simple to build, provided you can find the right transistors.
The quality of these 12 PCBs is brilliant. I'm quite confident Mr. Pass would approve them for a legitimate First Watt amp.
I'm still gathering some parts for this amp, hopefully I'll be able to start the building process soon. Eagerly anticipating ...
delivered within days, love the da store
I'm still in the part acquiring phase, but these boards are really nice! Can't wait to solder them up!
