I recently got myself some Grado sr225i's and I'm in the market for a DAC for them (Currently running them from an ASUS Xonar DG). I am interested in the TC7510 that I found on eBay (http://www.ebay.com.au/itm/370528529957?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_1405wt_1396). I've heard good things about them and it's very affordable.
I will also be buying a Little Dot 1+ (and upgrading the tubes and op-amp) to amp the Grados. Now, I know that the TC7510 -> Little Dot 1+ -> Grado sr225i will work fine, but I'm also going to be purchasing the Swan M50w 2.1 system that I intent to run from the same DAC, whichever one that will be. The reason I'm so interested in the TC7510 in the first place is because it's a sub 200 dollar DAC that has 2 outputs. However I've noticed that the two outputs aren't the same. One is Variable Amp and the other is Fixed Line. From what I understand the variable has it's volume controlled by the volume knob on the front of the DAC whilst the fixed line cannot be adjusted. I just want a decent DAC with two outputs; one for my headphone amp and one for my 2.1 amp. I have no idea if those two different RCA outputs are intended for different uses.
Will it be an issue? Both the Swan Speakers and the Little Dot amplifier have their own volume controllers, I just want to know if the set up I want to do is going to work properly:
/ RCA output 1 --> RCA cable --> Little Dot 1+ --> Grado sr225i
PC --> SPDIF cable --> TC7510 DAC
\ RCA output 2 --> RCA to 3.5mm cable --> Swan M50w 2.1
I'm quite new to this, so please excuse my ignorance If there is a better PC DAC to achieve this, by all means, educate me.
Thanks in advance!
