VTL 6.5 vs VTL 7.5


How much difference is there between these two preamps? Is the 7.5 quite a bit better sonicially than the 6.5?

Power supply is removed, thats about the main difference. But you should find out if there are any sonic differences from the VTL. My understanding is it is just the power supply being in it's own chassis, which is a big deal sonically speaking.
Also a different grade of caps in the 7.5 as compared to the 6.5 and the 7.5 I believe has a sort of floating circuit board where it is somewhat decoupled from the chassis.

7.5 is tops.
Very few differences

(1) Output coupling caps are smaller on the 6.5
(2) 6.5 uses unshielded relays; 7.5’s are shielded
(3) Of course the 7.5’s power supply is physically separate.

Luke Manley claims that the 6.5 delivers 85% or more of the 7.5 sonics – very, very close.
Hi,
I am trying the 6.5 now...latest version...might consider the 7.5 mkII...is it worth the difference....I have put some NOS tubes....seem to make a significant difference...clear top RCA...also some GE 6189W mil spec....and some Sylvania tubes...working my way thru them....any suggestions?
