Will a more resolving CDP improve my system?

One way to test if the preamp is limiting the resolution of your system is to try connecting the RCA outputs of the Arcam directly to the power amp. Of course you will have no volume control, but if you select the right piece of music you will get an idea.

If you play Bolero, which starts off at a very low level, and have the remote handy, pinky on the "Stop" button, you'll get some way through the piece before you have to stop. Try it that way and with the pre-amp in place.

Regards,

I secnd Metralla's advice. Play the quiet piece WITH a pre FIRST and check out how long the low volume lasts. If you do not have Bolero, find another piece of music that increases in volume very gradually.

the Belero test is well known and very effective. The totally transparent sound will shock you. You may not be prepared for the results, good or bad!

Generally yes. I think there is a general misconception that within a tight budget you skimp on the the source when it should be last think you do so: if the source signal doesn't start out right, doesn't matter what you do at the end of the chain, logically speaking

Chiho, the pv10 is as described above, lush, warm, full-bodied on the bottom end which gives the system a pleasant musical presentation. I had one for years. More resolution will definitely come from an upgrade in the pre, however...more resolution may expose something else like your CDP? Not familiar with yours. What has worked very well for me is a smooth, warmer, digital frontend, very analog-like IMO driving more resolving components with reference wire. It has taken me a while to get the system to a level that for me is incredible but it's there. My philosophy right or wrong is this, I listen exclusively to redbook CD's. My player, Meridian 200/263 has always played this format at a very high level, since 1993, until the software improves I am happy getting the same excellent sound out of my hardware and improve things downstream.
