My first kit from diyaudio and not my last. I’m a Pensioner with a lot of time. I’ve always been in to HiFi but never electronics so a year ago I thought why not and now I’m hooked on this. I ordered a F5m too and testing that one tomorrow.
I made mono blocks with the superb pcb you are selling and the fets.
i am astonished by the results. they have only few hours and they start to open up!
Thanks Mister Pass and DIY audio store, what you do is revolutionnary.
I just completed my build and testing of the Aleph J amplifier. It’s occupying the 4U chassis of the F6 amplifier I built and have been enjoying for the past 18 months. I liked the F6 a bunch, but at times I wished for more authority over my speakers. The Aleph J certainly has that! It sounds great. It’s detailed, has a nice soundstage, and packs a punch. So far I’ve tested it with B&W 686 S2’s and a vintage pair of ADS 1230L’s. The Aleph boards were top notch, and the build guide was very helpful. I’m grateful to the DIY Audio forum for for the great service and products it provides! Keep up the good work:-)
Just finished my Aleph J in a 5U case (big and heavy sitting on my bench) and the sound is just beautiful with my Focal Sopra 2 speakers. Those demanding beryllium tweeters just sound sweet as honey with the Aleph J and the low impedance dip in the base region is a piece of cake for this monster.
Only added the excellent Neurochrome speaker protection to be feel more on the safe side.
Before this I made me the F6 that is also one excellent amplifier to keep.
P.S. the service from the DIY -store is world class!
Great Kit it all worked first try. It's a great price and you know you get genuine parts. So highly recommended!!!
It came nicely packed and I actually bought this FET Kits separately and bought the other parts to complete the whole Aleph J Amp. The sound signature of this design, thanks to the very generous Mr. Pass is so unique with holographic and engaging sound stage, well controlled lows and very sweet mids and highs.
This is my reference DIY amp now after building the ACA and the F4. Its is just a cut above all the ones I built. So worth the time and money and I am delighted I decided to build it.
My Aleph J
The kit worked flawlessly. Thanks very much!
I recently completed my Aleph J build and I have to say this has become one of my favorite amplifiers to listen to amongst my Pass DIY Sony VFET Class A amp and my McIntosh MC240 vacuum tube amp. This amplifier has exceeded my expectations. When I listen to this amp in my system, I am impressed with the fine detail, the separation between musicians within a very large, deep soundstage, and the tone and timbre.
Love the thickness and overall quality of these boards. Great layout too. Thanks!
I first came across the dii-audio, bought the pass-alep J board and the FET, and I bought the trans and case separately.
I'm happy to hear as good a sound as I expected.
There was a problem with grounding and RCA wiring, but fortunately it's been solved and I'm listening with great satisfaction.
Now I'm going to try the preamplifier.
Thank you. Everyone.
Ainda não montei o Kit.
O aspeto visual é muito profissional.
A aquisição de materiais anteriores, foram muito positivas.
Daí.... A minha confiança total
The Aleph J is a great amp.
Transparency , musicality .
Bass are deep, articulate, punchy and well-toned. This amplifier shows no harshness or agressiveness.
This amp drives m'y ATC loudspeakers with autority
Thanks mister Pass
This was my first amp build and with the high quality boards and components, it was very enjoyable. I purchased another Aleph J kit and the M2X boards and power supply boards. I believe the boards are bulletproof and extremely well laid out which allowed a greater chance of success. The DIY Audio forum is extremely helpful, shout out to 6L6, and other for the build guides, not exactly paint by numbers but very well done.
My eyes are bigger than my stomach and I buy too much. I'll get to it, certainly, but haven't yet. Nonetheless, I'm sure I'll be happy with everything. Thus far all that I've purchased from Diyaudio has been well supported and as described. The electronics world can, it seems, be a tough crowd. I sometimes see stones cast at Diyaudiostore.com and Nelson Pass. The same two are responsible for me daring to try and succeeding. I'm very thankful despite not having any measurements of what I've built to date.
The amp is fantastic but I was worried about getting replacement parts so I squirrelled these ones away.
I love my Aleph J so much I bought a build kit just to assure I’ll never be without should the one I have meet an early demise.
It’s an Amazing value!
I built the Aleph J with a dual mono block universal power supply. It was replacing an Outlaw integrated amp which was very good. I was expecting the Aleph J would be somewhat of an improvement. I was wrong. It was an amazing difference. Dead quiet, detailed and transparent. I also built the Korg B1 preamp to use with it. It made a hearable difference as well. I can't imagine getting the upgrade itch but you never know....
My first impression was:
1. Incredibly fast delivery, far above my average experience so far.
2. High quality PCB
Feedback from me:
The current PCB is more than enough to build a high-end power amplifier, however Audio DIYers like to experiment, therefore the lead spacing of components on the PCB should be larger or longer, especially in order to accommodate top-end components.
All the hard to get semi conductors for an Aleph-J build in one easy package. What's not to like. They sound great 👍
Came in timely fashion. Clean, authentic parts. Will use them soon. Good service.
Decided to assemble a second Aleph J. Want to make it a present to a friend. Ordered PCBs and received them extremely fast. As usual, all parts are exceptional quality. Still working on the project, but will finish soon :)
Ultra-fast delivery, excellent parts, no customs issues (as always!). AJ playing again (had blown 2 transistors due to silly handling).Thanks a lot!
Component parts for my pending PCBs purchased earlier from you 🙂.
Fast and easy delivery, well wrapped, thanks 🤓.
I am very satisfied with the product!
