Good afternoon everyone,

I was hoping someone could give me some good information and opinions about my personal system. Here is my current audio/music setup:

WAV Files
Iomega ScreenPlay HD Multimedia Hard Drive
AudioQuest Hawk Eye S/P DIF
Primare SPA21 Surround Amplifier
AudioQuest Rockefeller Speaker Cables
Vienna Acoustics Strauss Speakers

PS Audio Power Port AC Receptacle
Furman Power Station PST-8 D
Shunyata Research Sidewinder Power Cord

I am considering the addition of:

Beresford TC-7510 or TC-7520 or TC-7520 with the LM4562NA
Kimber Kable Hero Interconnect Cables

If I theoretically had the option to buy a brand new TC-7510 at a severely discounted rate, would my system instead sound better enough by purchasing either the TC-7520 or TC-7520 with the LM4562NA to make the higher price worth while?

Thank you everyone and I really appreciate your help!

Sincerely,

-Adam Wright
