Im trying to research to see what would be a good cd transoprt for my system to upgrade from my Oppo Dv-980H, I have a dacmagic. Ive narrowed it down to Nad C515, 545, Marantz CD-5003 and Cambridge Audio 550C or 540C. I own the cambridge 640A with Monitor audio rs1's.
IMO, it is highly likely you'll hear very little if any difference between your Oppo and any of those players. I actually preferred my Oppo to my NAD as a transport when I was using my CIA dac. A computer or music streaming device (like a Slim device) or even an Apple TV might be good options to consider.
I want something I can take wma lossless and wma protected files ( Zune pass) and stream them to my audio system. i have an xbox 360 running optical to my dacmagic but the quality is very very poor from the xbox.
I wonder why the sound quality is that bad. Probably jitter? If it is jitter, have you considered the Monarchy DIP or a similar device?
I've contemplated one, but I'm waiting to figure out what DAC I'll ultimately end up with. If the DAC re-clocks, the DIP is redundant. If not, it reportedly makes a very big improvement. And it converts optical to coax, which is a better connection.
The Monarchy DIP is a re-clocking device. It'll also convert optical to coax. By re-clocking the signal, it greatly reduces jitter. I read a review that measured the jitter reduction of a few different devices at the time, and the Monarchy DIP was one of the best. It reduced optical jitter by something like 85%. The Theta TLC is another such device that was measured, and reduced optical jitter even more.
Jitter reportedly causes several audible things - glare, etch, hash, reduced soundstage (almost compressed sounding), and so on.
If jitter isn't the issue, then these things won't solve any problems.
The Monarchy DIP (there's a few different versions - DIP Upsampler, DIP Combo) and Theta TLC can usually be found on Audiogon for a decent price. I don't think Theta makes the TLC anymore, but Monarchy still makes the DIP. Check Audio Advisor. They had a demo one for a few bucks off. You have to go through all 8 or 9 pages to find it.
Ill check it out im also looking at getting 340C as a transport. but im still doing some research. i ant my system to be more on the warm detailed side. id like to reveal more in the recordings. I was able to demo a nad 565 but on a high dollar Nad pre/amp combo and Thiel speakers it was very revealing.
