First Post, Looking to buy Amp& Pre, $7,000


The first thing I'd like to say is "Thank You" to all the people on this forum for their knowledge! I've learned so much from my daily trip to this wonderful site.
The reason that I,like many others I suppose, have not posted before is that I think there are so many people here that have so much more to offer in knowledge and experience than I do. Well..... on to my questions.
My system consists of PSB Synchrony One speakers, A VPI Classic tt with a Dynavector 20XH cart. A Simaudio LP3 phono. Cambridge Azur 840 CD player.
My current amp is a Denon AVR 4806,that also doubles for Home theatre.
My current system sounds very good, But.... I'm wondering how much better could it get? Will new amplification be a huge improvement over what I've got?
I would prefer to buy used because I think I could get more performance for my money.
I listen to Rock,Classic Rock,Blues, and Jazz.
I would prefer a sound that is neutral,but a shade on the warm side. I suffer from tinutus in my right ear.and any high notes that are too dry, or too bright, irritate my ear!
I also need a pre with HT bypass,as I have everything in the same room
Thanks,
Mark

The reviews of Moscode were great, But in John Atkinson's mesurements he didn't think it would be a good match with speakers rated at 4 Ohms,as mine are.
Also, in his measurements of the Synchrony One, said that the speakers would dip as low as the mid 2 ohm range at two frequency levels So I'm re-thinking,and trying to remember my goals, to match the amp's sound to my speakers AND have the treble where it will be pleasant to my ears. Oh yeah, lots of powers too.
I'm leaning to a McIntosh, maybe a MC 402.
What do you guys think???

The levinson 383 is a good choice for integration into a home theater system. It can be fully automated with the creston system, has the bypass and by and large it has the best operating system I've used. However it's downfall is power, it just won't play extremely loud. That's why I bought the 7000 but it's for two channel only.
