I own a VT200 Mk1, which recently did some mods inside the unit:
-replaced the infinicaps and wonder caps in signal output coupling caps and power supply bypass for stealth caps
-The original power cord replaced by transparent reference xl power cord.
- Replaced all tubes by using svetlana special edition
those improvements transform this extremely good amplifier into a new one vastly better than original.
-Much better low end, tight bass, extremely dinamic, some veil removed which mades a extremely accurate amplifier.
- the mids are to die for, clean as the best, articulated and effortless.
- top end is too another area vastly improved, in fact I don't know from what I heard a better top end out there.
- the soundstage increase and much better defined.
the system is:
VPI Classic turntable/dynavector vpi special cartridge
Audioresearch ref 3 preamplifier
Meridian G08 CD player
Nordost quattro fil balanced interconnects
transparent loudspeakers speakers cables
