Any Eversolo Amp F10 owners out there ?

I forgot to add that I am also using aftermarket power conditioners and cabling with the AMP-F10, which obviously helps it perform at a higher level over stock. 

I realize I am reviving this thread after a month, as I was spending time this morning looking for reviews on the AMP-F10. 

I’ve been an Eversolo for a month now and have the A10 and F10 combo. As a dealer of many very high end brands, I will say that this combo truly impresses me, especially at its price point. I don’t believe any entire chain of electronics (streamer, DAC, preamp, amp) can beat it sonically at its asking price of ~$6,300. Together, I find it to present in a very natural way. Great tonality, good separation, enough to be holographic and help speakers disappear, a hint of tonal richness, and pretty strong control over speakers. 

The AMP-F10 has no problems controlling my Vivid Audio G1 Spirit which dip down below 3 Ohm, but of course my reference T+A amps deliver better grip, a larger stage, and improved imaging for being 10x the price. The amp is detailed and articulate, but is also on the warm side. One amp I might compare it to at a slightly higher price point is the Cambridge Audio Edge W. In my comparisons, I prefer the tonality of the AMP-F10 a bit more. It is warmer, a bit more harmonic. Detail retrieval is largely similar, though moving to the Cambridge EDGE M monoblocks results it a higher league of resolution and linearity, albeit at 4x the asking price of the AMP-F10. 

The Eversolo combo isn’t as “endgame” as my reference stack overall, but I do believe its performance is very balanced across the board, whereas some manufacturers overindex on resolution at the expense of musicality and vice versa. 

I also have no doubt in pitting the Eversolo stack against other electronics double the cost, like the EDGE W.

@oddiofyl I had the same concerns with Eversolo in the past, but they recently started working with a U.S. distributor in order to overcome some of the challenges in the past. They are making an active effort to improve upon their communications and support, and I have found them to be very easy to work with. I have already suggested a few new features that they are willing to investigate and/or implement.

@oddiofyl That sounds like an unfortunate story. Just curious, what product specifically did you have issues with?

@oddiofyl That is unfortunate for sure. I’m aware that the McIntosh DAC1 module present in the 8950 and many of the preamps have their own USB connectivity issues or their own, so perhaps the issue is more complicated than it seems, especially if the unit can connect to other DACs with no problems. This wouldn’t be the first time a firmware has botched something that was working previously, and sometimes, a firmware rewrites core functionality that is not easily reversible, which is why it is not always easy to roll back (I used to be a coder so I have some experience on this).

That said, there is no excuse for the lack of response you received on the Eversolo team on this. There should have at least been some communication to validate the issue and have either a clear path for issue logging, investigation, and resolution, or at least communication to show why they may not be able to offer a repair. Were you getting responses from them in the beginning? If not, I have to wonder if messages were going into a junk mail folder, but I’m guessing you checked there.

Knowing you, I’m 99% certain you looked into this but have to ask the obvious question - have you updated the firmware on the MA8950? I know that one of the later builds addresses some of the USB quirks the DAC1 units were known to possess.
