@Pinnocchio
I am glad that your setup is working in perfect condition now, grounding issues are usually problematic in some specific setups, or with specific amplifiers.
@Maty Tinman
I would love to send you two SMPS-600 units at cut off price if you are interested, like 50% discount, let me know if you are interested.
For the upcoming new SMPS versions.
SMPS350
SMPS630
SMPS1200
Something completely new, with many added futures.
Thanks for all

Hi Do,
I'm pleased you've noticed that
Acoustic instruments and vocals - it shines the most with those kinds of music material.
Also, try to listen to some good recordings of a big band - like Les Brown's Band of Renown in high resolution - you will be able to distinguish practically every instrument in the band. Precise positioning of the sources within the soundstage. Plus very nice tonal balance - delicate highs, natural mids, rich (but not over-damped) lows. Acoustic system is not a "point source" anymore - it's a musical instrument by itself.
Happy New Year and best wishes!
Cheers,
Valery
Yes Hugh, this design is the great learning for me in terms of the priorities, important for the true sound quality. I'm moving forward from there, exploring non-traditional methods of error correction.
The "formula" I have in mind these days is more or less the following:
A limited number of high-quality (linearity, bandwidth) stages - local feedback in each of them - and then just a little bit of "overall housekeeping" with an efficient error correction mechanism. Optimal output impedance is also important - no overdamping!
Some of our offline discussions are really inspiring - I appreciate them very much
Tout à fait d'accord - we have to be very careful with gleebal foodbuck, especially in the power amplifiers
Happy New Year - lots of success, joy, happiness, health, and energy to you and all your loved ones
Hi,
Having +/-50V at the rails, 63V caps will be fine. Just make sure they fit the board holes properly. 100-160V in the BOM is a combination of convenient size in general and availability in our stock in particular (470uF 160V)
Cheers,
Valery

Thank you, they feet well big sized BG caps. I only can use with this project because of their size, I believe it worth to use them here.

Yes, the boards V1.3 are in production. PCBWay had some production hold recently - the boards are still in production.
I will send you a pair as soon as they arrive.
Thank you Valery!
I have the feeling that this box will not remain empty for a long time.
Thank you Valery!

Sounds like a very good plan!
Hope you will "feel the difference" this amplifier brings to music reproduction quality
Good for you Thimios, you are on the right track. When I designed pcb's for a living, it was the ME who gave us a board outline drawing after the prelim mech was designed, it was never the other way around. If we could not fit the comps on the provided board outline, then we went through the reiterative process to nail it down.
Hi Valery, hope all is well with you. I have some boards being fab'd at JLC right now, probably best to stick with the std default process to get them through faster, looks like they will meet their 2-3 day build schedule, I see that they are in test right now. Have to use DHL in order to guarantee a timely delivery, can not trust the postal method.
take care Rick
