Holo Audio Spring (Kitsune version)

I owned the L3 Kitsune Holo Spring DAC for a short while. When I got it a few months ago, it was fully broken in, with some 400+ hours. At the time, I also had a ExaSound E12 that has been my daily DAC for the last couple of years. 

I was really disappointed with Spring. It was like "meh".... really kind of boring and uninvolving compared to what I was getting from the ExaSound. Note that I only tried the USB input, and I decided not to buy the seemingly necessary Singxer SU-1 ( and hearing that the power supply needs to upgraded) and HDMI cable.

I have since upgraded to an exsSound E32, and love it! It's quite a bit better than my previous E12 it replaced, thanks to a generous trade-in from ExaSound. It's  fantastic DAC that makes my digital music (Tidal, Roon, HQPlayer, Music HD) sound real, natural, involving, etc. 

BTW, I power it via a 12v SLA battery all the time. No need for fancy power supplies unless you feel the need to spend another $400 to $800.

A ton of people love the L3 Spring. I wasn't one of them...

No rant.... just offering up my opinion, and nothing else, in answer to the OPs question, about comparing other DACs to the Spring DAC.

As I stated, in my system, to my ears, the ExaSound DACs are much more musical, involving, and fun to listen to vs the Spring.  I tried. Didn't float my boat. YMMV. 

@nitewulf ... just single ended; my system doesn't support balanced mode. It seems most people highly prefer the HDMI input of the L3 Spring DAC which I did not try. My comparo was only USB.

The T+A was also on my list, but since I was able to trade in my E12, I went with the E32 instead. Exasound has developed a custom ASIO driver for Mac OS X, so it's nice not to have to use DOP to get DSD, rather I get native DSD because of the ASIO driver, up to DSD256. I don't have the hardware to support DSD512 anyways.
