Hi all,

more_vert
I am new to all of this and need your help. I purchased the Thx 789 and HD6XX not realizing I need a DAC. Which one should I buy? When I buy one will it come with a cord that connects to the amp? I am trying to google all of it, but I am not getting the answers I need.

I have the hd6xx as well. I also use the thx 789 amp I purchased the topping d50s (make sure the “s”) its a very good DAC (no amp). the sound is tremendous. Buy good cables note, the d50s has coaxial, optical, and usb b for inputs, no rca inputs (has rca output though). Make sure of your source connection before you buy. Also, need to purchase a 5v power supply. I paired mine with the topping p50 linear power supply for an exact match, but there are cheaper options. However, the two make a mini stack that looks great sitting centered on the thx 789... soundwise, the d50s is exciting and is a big step up from the 100$

Thio, looking further into the JDS EL-DAC-II, it looks more like an Interesting engineering change moving forward in design. They are using an LM340 as a current source for performance/stability rather than voltage, driving the AK4493EQ, into a nice NJR opamp. It is part DAC ‘chip’ and a lot of implementation (engineering) that makes a better DAC, as well as simply listening & fix'n...

Depends on your budget. Until 300, 400$ you have Grace SDAC on massdrop, also SMSL SU-8, Topping D50, Topping D70 is very good but is 400$+. If you have a bigger budget RME ADI-2 DAC and Denafrips Aries and Topping D90. In my opinion i wouldn´t spend more than 400$ on a DAC before knowing if you need one. Hope i´ve helped.

Under $200 makes sense to me for a budget. The Grace balanced dac doesn't ship until Aug31. The SMSL SU-8 ver2 just came on Drop so I think I will buy it. Thanks for your help. Now I just need to figure out what cables hook the dac and the 789 together. I was going to buy these: https://drop.com/buy/fanmusic-c006-xlr-interconnect-cables but they sold through.

I think you can find those same cables on amazon.

Need to know your budget. If you want to stay cheap, go Schiit Modi 3 or Drop x Grace SDAC. They're more than good enough for the price. If you need a cable, just get a cheap RCA interconnect from Amazon or somewhere. At this price, I wouldn't worry about $$$$$ cables (and in fact, I advise against it unless you really know what you're doing. Great analog cables really only make a difference on truly TOTL, resolving systems).

SMSL SU-8, hands down. Make sure to pick up a pair of XLR cables so you can get the full benefit of balanced.

I just look at the importance of your earphones and you would need a Amp to push more than 300 ohms minimum. I would recommend a 600 ohms.

Hi there I'm not very familiar with your headphones but I hope my answer would give you an idea of what Amp you could get. Notice that your earphones have an impedance in ohms it could be over a 100 for example and you may look around for amps that have a resistance over your headphones ohms. Thanks
