Getting more from my DAC


I need some advice. I've put together a mid-fi office system over the last few months:

Sony XE500 CDP acting as a transport
MSB Link DAC III with 24/96 upsampling
McCormack Micro Integrated Drive amp with upgraded PS
Tannoy System 600 nearfield monitors

Toslink cable between transport and DAC. Ratshack gold series interconnect between DAC and amp. Audioquest Type 6+ wire between amp and speakers.

I was fairly happy with this system until I tried connecting the Sony CDP directly to aux posts on the amp and switching back and forth between the CDP/DAC combination and the stand-alone CDP. On a straight A/B comparison, using the selector switch on the front of the amp, I hear almost no difference, even with well recorded piano music/female vocal/jazz.

This is disappointing. The amp is low powered but pretty transparent, I believe - as are the speakers, which were designed as pro monitors and have a reputation for being revealing. So why aren't I hearing a more perceptible improvement - change, even - in the sound when the DAC is introduced into the system?

Are my crappy cables strangling the DAC? Is the transport too cheapo to let the DAC do its work? Do I need to follow the MSB/Modwright upgrade path before the DAC will really shine in my system? Or is the whole system a bit too bargain-basement to benefit from a decent DAC?

Words of wisdom gratefully received.

Try the Stereovox HDXV like Photon46 suggested. It's a great digital cable. It's only $100.00 and may be purchased (or just auditioned first) from The Cable Company. Ask for John Pharo, he's a nice and knowledgeable guy who can really help. The Cable Company's phone number is 1-800-fat-wyre. The website is www.fatwyre.com.
The transport is the primary problem. It can definitely benefit from mods, but you will probably need to put a Superclock2 in it at considerable expense. A digital cable is also recommended, and a good one. You can come really close to the digital cable performance with a glass toslink such as this one:

You can also get the MSB modded. I recently modded a Gold version and it turned-out really spectacular.

Select your modifier carefully. A digital engineer will have more knowledge about transports and S/PDIF interface.
Heresy here....but, could it be that there isn't as much difference between DACs/Players as is touted? I've had similar experiences over the years in a roughly equivalent system switching between Rotel/Theta Theta/Sony Rotel/MSB and Pioneer/MSB. I still keep upgrading and I think my system sounds better each time, but on that A/B test, I don't know and it makes me wonder....
I would recommend you try a Monarchy audio 24/96 upsampler. Really improved my MSB. Plus, since I think your cd player is toslink only the monarchy upsampler will jitter reduce and allow you to use coax into the MSB. If you buy through them I think you get a decent cable as well. You may also want to try some cheaper Harmonic Technology cables from dac into the amp.

My most important advice though is that if after trying some things you still don't hear a difference don't feel bad about downsizing and buying more music.

Tarsando - this is the impression one gets when listening to stock components, particularly mid-priced such as those you have, although some do sound a bit better than others. Modifications however make a HUGE difference. This makes these sound like real music. Mkae sure you pick the RIGHT modder.
