I'm not exactly sure what a DAC is, and I'm not sure if the sound quality of CD's would be better with one played through a tube headphone amp. I'm new to these and the upsampling, oversampling, non oversampling, etc just confuses me completely. The setup I have now is just a sony dvd player...

Just bought these for about 17 bucks shipping included off of ebay and I was wondering if there was any real sonic difference between them and the budget blue cable ar series, and also, just how good are these cables? I haven't been able to really listen to them since my headphone amp is being...

Ok I'm not really a power cord guru when it comes to knowledge, and all I know is that I want to replace the crappy cord on my LDII, so here is the question, is it worth to pay the extra money to get a Bok, or should I just get a Birth because I probably wouldn't be able to tell the difference...

This is my set up Ipod 5g -> line out dock => acoustic research stereo mini to rca => Little Dot II => Grado SR-225's...the power cord is connected to an old radioshack surge protector/noise suppressor, and it is not this surge protector either I know because even before I moved the protector...

I just received 3 different tubes in the mail today, 2 are International C Brand NOS 1S5 tubes, and 1 tube was a Sylvania NOS 1S5 tube also. So when I plugged in the pair of International C tubes and I listened to it out of my line out on my iPod, I expected bliss...But what I got was a sound...

Does anyone know of any high quality electrical cables that can be used with the LD2? I'm trying to get an all around better performance out of the amp, I have upgraded the mini to RCA cable, hopefully soon getting new tubes, and AC cord is the last thing on the list. Preferred to be less than...

I have had my SR225's for about a month and I love them, they sound great with my LD2 amp, but because of head-fi, I want to upgrade them already. Should I go with the SR325i's or the RS2? I know the SR325is have their own sound signature and the RS2s are about 200 dollars more than the latter...

What are some good tube replacements for the larger 2 tubes in the back and the smaller 2 tubes on the Little Dot II? I will be receiving mine very soon and I want to have some back-ups in case they do not work or are not good enough.

Sometimes, when I listen to my speakers when no music is playing (and now headphones through my new little dot micro), it seems that sometimes I will hear a series of short little hisses, they seem to get louder as I turn up the volume. At first I thought it was only my computer but now it seems...
