decooney,
I really can't answer your question right now. I've had the CODA for about 6 weeks and the Transcend for about half of that. In addition I've just received an Aric Audio Motherlode XL preamp, so I'm really testing 3 components at about the same time. The CODA is broken in, the Transcend is about broken in as it was the same exact unit that was reviewed by Bob Grossman at "Enjoy The Music" with a few new upgrades, and the Motherlode XL is just recently installed.
The nice part is that the Motherlode XL allows for both amps to be connected at the same time, and I can switch back and forth. Both amps are brilliant and really easy to listen to, the best amps I have ever owned by a good margin. You can read my review of the CODA on the S5.5 thread started by Teejay here on Agon, and Terry London (Teejay) will have a review on it sometime soon at Stereo Times.....and you can go back and read Bob's review at "Enjoy The Music".
I never say never, but at least for the next bunch of years, I am off of the preamp/amp upgrade cycle......both amps and preamp are BRILLIANT. I don't know that I could review the entire combo, as I've run out of superlatives in my previous reviews (Clayton Shaw Caladans on Agon and the CODA S5.5 review). But for the money ($3,000 for Caladans, $6,000 for the CODA, $4,000 for the Transcend, and $6,000 Motherlode XL)....less than $20,000, I'd put this combo up with anything I've heard for less than $50,000. That is an opinion of course, but it's certainly up there
