Which DAC Under $300

[MX117.MC7150]

Very pleased with my FiiO K13. A few $$ over your limit, but well worth it to my ears.

I just received and hooked up a new SMSL PL-150 being used as a transport, and the new SMSL SU-2 DAC, both connected with an optical cable. I just started listening and so far I'm liking them both.

.
Yesterday I received a new SU-2 to give the tubes in my FiiO Warmer DAC in my main system a break. I typically run my gear twelve or so hours a day. I’m into the second day and the SU-2 really sounds great. A hundred bucks! You can’t beat that for a DAC that is just a DAC with no bells and whistles which is exactly how I like it.

Both my FiiO Warmer and Geshelli J2 are the same way. All of these DAC’s have RCA and XLR outputs that work simultaneously, which I utilize to great effect. The Geshelli does have three fixed volume levels, high, medium, or low which is helpful if you connect directly to an amp that has a volume control. Setting the fixed volume to medium or low allows for greater and more accurate volume control of the amp. I use it that way in a secondary system.

Anyway, so far the little SU-2 is a fine piece of gear. Oh yeah, I’ve tried both coax and optical inputs and both are excellent. Recommended.

They did omit the USB jack on the SU-2. It wasn't a deal breaker for me since I just wanted a straight forward DAC for my main system.
One review I read stated the difference between the even cheaper now SU-1 and SU-2 was that the previous version of the processor chip in the SU-1 had a bit of a warmer tone to it and it has a USB jack.
I'm still very happy with the SU-2. I see you have a ST-35 as well. I also have a slightly moddified VTA ST-70 and VTA M-125 PPP mono blocks in my main system. But the little ST-35 is my favorite. The EL84 type tubes are my favorite sounding power tube. I'm using Sovtek EL84M's in mine. They're just re-labeled Russian 6P14P-EV's. I'm using Reflektor 6P14P-K's in a heavily moddified Magnavox 9303 PP console amp, and a scratch build SE amp.
The ST-35 is an awesome little amp.

I bought a Fozi ZD3.

I use a ZD3 and got a good bump in overall sound quality from replacing the supplied power supply with a regulated, linear one. I use a budget friendly power supply I found on Amazon for $15 along with a plug adapter to allow it to fit in the ZD3's power port. The six watts this power supply outputs runs my ZD3 just fine and I have never had a single issue with it for the past fourteen months I have been using it. This might be the best return on sound quality for the money spent I have seen personally. Links to the PS and plug adapter are below.

Yup, great amp! Yeah, I use some NOS 6P14P-EV too along with JJ gold pin 12DW7’s for the drivers. Great sounding rig.

I use JJ signal tubes a lot. Recently I replaced the JJ 12DW7's with some NOS
GE 12DW7's. They were only a buck or to more than the JJ's. I really like them.
The JJ's sounded good though.

Yes, those NOS drivers are what Kenny Russell shipped with the amp. They were just fine until one of them started acting up. Oh well, life with tubes.
