Ok - I got some other vinyl and have been listening to the turntable for 3 days now, off and on, seriously, casually and as background music. This should take care of those who got hung up on the one part of my test were 40 second bites were used. I have been working at home a good bit lately so I listened a whole lot. So here are my thoughts at this point:
It doesn't have as much definition as my CD players and the rhythm and pace kind of suffers as a result. The toe tapping is induced but not as much as my CD players where their better control of leading edges gives the music a pulse of life the turntable can't quite match. Its ability to keep complex music clear and layered is another shortcoming, probably due to the same problem. The differences are slight, of course, but they are there.
However, the bass is excellent - good weight and strength and probably betters my digital sources in many cases. But I am not a bass freak and pace for me plays a bigger role in my decision to keep something or not. The coherence, soundstaging, high frequency extension and midrange smoothness were all basically like I am used to hearing - which means, very good.
When I take it back to my dealer, I will bring my Sony or Prima along too so we can hear them there together. Though some of you will dismiss this test because it doesn't go on for days, I am curious to see if anything will change in another system. But my system is what counts so it probably won't change my mind regardless.
I really enjoyed my time with the Pro-Ject. The problem with definition is an issue though because it hurts the musicality and "liveness" which are core requirements for my tastes. Maybe a different turntable or cartridge would improve it but I already have better for less money so I don't have a drive to try another analog setup. I am satisfied with the conclusion that my CD players are all I need. I am going to buy a few hundred CDs instead of the turntable, disc cleaner, and new LP collection. Thanks for all your comments.
