Low Cost DACs

So I don't know about the weights although I agree that the unit should sit firm on the table, but it does appear to "break in" after about 50+ hours. Sounds less "brittle' and a bit fuller. I think maybe at some point I'll play with cables as they certainly effect overall output. For $100.00 with nothing other than my OPPO to compare, I'd say it's a decent deal.

I usually have my Modi 3 in a stack with the Vali 2 on top.  It's not a lot of weight, so I can't really say if it's been a help.  What I do know is that any dac I've got sound mediore when plugged into my avr.  They are sound much better with the Vali 2 and my Grados.

I think it's because the AVR has too many compromises to the audio quality, and perhaps the preamp circuitry was one of the compromises.  I run the AVR in direct mode, which apparently doesn't process the signal in any way.  It doesn't even extract anything to feed the subwoofer.  

The dacs also sound much better in the 2 channel rig with a proper pre.

Currently mu Modi3 is direct RCA connected to PrimaLuna Integrate. It's sounds okay but I'm wondering is a different Lap Top to Modi3 cable might help. using the stock cable. .

I was using a generic 6 foot 3.5/RCA to my Vali. I went with an 8 ft. Blue Jeans Cables BJC MSA-1 Audio Cable. It has made a noticeable difference. 

Would a more expensive cable have made a bigger difference? I doubt enough to justify the price.
