I've recently been given the opportunity to listen to the Burson V6 Classic and the V6 Vivid in my Whammy. Prior to that, I went through many monolithic opamps. The discreet circuit V6 Classic came out the clear winner. The V6 Vivid had a character that I found even clearer and more open than the Classic but not quite as smooth for my taste. I listened using closed back dynamics, open back dynamics and open back planar magnetics. Interestingly, the V6 Classic provided my Sennheiser HD650 headphones with the most balanced, smooth and listenable sound I have ever heard from them, almost like the Classic was designed expressly for them.

The UNIVERSAL POWER SUPPLY PCB's or very nice quality boards. I would recommend that the ground be isolated on each half of the PCB so two independent +/- supplies can be created for power multiple analog circuits. If you look at the PASS DIY 40 watt amp and split the ground so each 1/2 of the filters and supply 2 independent voltages. To support a Transformer with two secondary and each secondary having a center tap. I do like all the options the board presents, thumbs up.

Super fast delivery to Germany, nice Board. 10/10

Quality parts already matched eliminate the need to buy extra and match them myself. they work well and buying from diyAudioStore is simple and fast.

The preferred chassis of William Alfred Noice. It's got holes in all the right places. Noice.

I have built two of these and in both cases outstanding results, one the second one for my son I put the 15v transformer in to make it run cooler, there is no sound difference in the two units. The other has a 22v transformer in it. Used 833 Op amps tried various found that I liked these the best. I love the sound through both my SennHeisers 600, and really love it through the HiFiMan Sundara. I would have to say its the best result I have had with a DYI build and also with any commercial Headphone amp. Build it you will not be sorry. The front panel is miss spelled but that's the beauty of a DYI you can do what you want to it.

Received my Korg Nutube B1 kit and I am gathering all my parts to build a 24v regulated PSU for the unit. I'll be mounting it in my own wchassis with a 4 input option.

I'm a novice builder (one Akitika power amp prior to this build) and I found construction to be easy and fairly quick. I spent more time designing a 3D-printed case.
I love the ability to tweak the level of second-harmonic. After a quick listening session I went for 13V and a modest level of H2.
Sounds great! For well-recorded material the stereo image is spectacular. Less well-recorded material is equally obviously mediocre or worse. But overall, I am enjoying revisiting CDs, some of which I have not heard in many years, and discovering detail that I wasn't previously aware of.
This has been a great experience for me! Thanks to Nelson Pass and everyone else who contributed to make this kit possible!

I am glad I oredered with my Dissipante chassis - it made constuction of my amp so much easier.

I recieved the chassis promptly after ordering. It arrived carefully packaged and was easy to assemble. The quality is top-notch. I solved the feet mounting "problem" by simply using longer M3 screws through the feet and the bottom panel mounting holes. Will buy again for future projects.

While repairing a channel in the F4 I had to unsolder and solder several parts repeatedly.
The board survived a hot iron. I've seen other boards come part after a single unsoldering of a part.

Having the mosfets matched in advance is a times saver and worked out well repairing a F4 channel.

What fun. So happy that I did this. Built 2 for XLR monos. Make sure you give them 8-10 hours of burn in before critical listening. I learned a lot by assembling these. An absolute joy to listen to. Special thanks to Nelson Pass.

Some rather large grounds require a lot of heat. I used Sn63/Pb37 at 780 degrees F. Careful with screw length and orientation if you're using a TO-220 diode and heat sink.

Delivery time was unbelievably fast- especially considering the chassis shipped from overseas. Easy to build- I just wish it had more gain.

Cheers!
