Ultra to Topping V70 Velvet to....

[RAAM]

Current setup plans, other recommendations welcome

Qobuz to Ultra (TV and BD player as well to Ultra as well as Ultra to Martin Logan sound bar)
Ultra fed by quality router via Ethernet cable (also TV to control song selection if it works, audio only through Ultra
USB out of Ultra to Topping V70 Velvet DAC via balanced cables
DAC out to Fosi ZA3 via balanced cables, upgraded op amps and 48V PS as temp setup to speakers
RCA out to sub amp(s) or powered subs

Amp(s) I might end up with dual mono ZA3 or build a custom higher end D class amp(s) for the mains, D class on subs as well and might be DIY.
Various speaker designs will be DIY built and tested to find the best solution in our full time RV, OB, SLOB, sealed, ported, etc...
Subs DIY, I have some great older Image Dynamics 15" drivers from my last home system I can build into the RV.
All cables DIY, great quality, low cost.
Room treatments as I can fit, look good, work the best I can make them.

Life long DIY with decades experience building very fine systems including car audio competition to extreme high quality levels. I know I can do something dang fine and not spend a lot of money on it as all but two systems I have done were so, only those two I went a bit nuts on in car audio.

Let me know what you think, ideas, recommendations, etc, please

Thanks,
Rick

I also have a beloved, highly modded, little tube amp I will give a listen to. Baby Sophia, 10 watt push pull, a very nice amp but I want to save as much energy as possible and reduce cooling cost though we use little now since converted to ducted Evap cooling, great to live where it works, $40 a month summer energy bill.


I have a much loved pair of Edgarhorn Slimlines, highly modded, in storage I would love to use, might not even test them here as a bit to big and need to be back away from them a bit more than we can do in the RV. Superb speakers, super efficient and got very loud but crystal clear and dynamic like only horns can do on the 10 watt tube amp. The late Dr Edgar was my friend, one of the nicest people I have or will ever of met.
