Audio Research SP8 MK II Sounds


Just bought an ARC SP8 on ebay and installed it in my system. Vocals sound boxy and a bit too forward to me compared to my McIntosh C20 preamp.
The SP8 was sent to ARC recently for a checkup, new tubes, were installed, etc....
The tubes provided by ARC are Electro-Harmonix, but the tubes in the Mac are Amprex Bugle Boy and Telefunken. Could this be the problem? Don't really want to spend the money for more expensive tubes if it will not rectify the problem.

My system:

Krell FPB 300cx amp
ARC SP8 MKII
Wadia 861 CD player
Mac MR78 tuner
B&W Nautilus 800 speakers

New to Audiogon and was also wondering how to contact other audiophiles in my area (South Florida)?
