Here are some computer speakers you might interested in. The ARX A1Bs might be a great 2.0 near field speaker for under $500.   http://www.theaudioinsider.com/specials.php?osCsid=038a5e30f097eef5895b63af9fb061b5

I had a 30gig 5.5 listening to losslees files through a Cmoy and various headphones and now have a Classic 160 and I can't tell the difference.

I listen to losssless film scores all day using an IPOD classic 160 and AKG 450's through a Cmoy. I really like the sound, especially the bass, which is necessary for film scores. I'm playing around with the EQ as I've only had them for about a week. I also have the ATH ES7s and MEE HT21s. I...

Sorry, I didn't see that in your post. I've never heard of a dual chip Cmoy. I might check it out but I'm leaning toward the C421.

Quote: Interesting. Can you please elaborate a little more? What's your source and what headphones?

I've had mine a week and love them. I also own the ATH ES7's and ME HT21's and the 450's sound better than both to me. I actually like the HT21's but the bass drivers are small and I hear clipping on deep bass. I listen to mostly film scores at work and they are not as full sounding as the ES7's...

Isolation is really good in an office environment. I use mine all day and I can hear people talking if they are close which I need but I don't hear anything else really. Of course it could be that I concentrating on what I'm doing and listening to the music.

Just purchased a pair of 450's last week on Amazon. for $67 though Electronics Expo and they are selling for $58 right now. I really like the sound. I have a pair of ATH ES7 and I like the 450's better. My souce is IPOD classic (160 gig) with lossless files through a Cmoy amp. I listen all day...

Op, I think it using a headphone amp sounds better. I like the fuller sound. I've been using the Cmoy for about 18 months with on-ear cans and I've used in ear phones too.

Is the C421 a significant step up from the Cmoy?

Check here http://www.jdslabs.com/store.php the Cmoy is a very nice portable amp under $150 and they also sell the C421 for $184. I've had the Cmoy for 18 months and really like it. I am thinking about moving up to the C421.

This is a very nice setup.

My setup is 2.0 system. To burn in you just let play for 50 hours straight?

I just got the V-DAC and the HRT+ yesterday. What is the burn in time for a DAC and how much time should it take? Anyone else compare these two DAC's?
