Meir, that is really a tough question to answer. I have owned all 3 more 
than once. I have also had TT's since 1978, so hopefully that counts for 
my opinion. As far as I am concerned, hands down, say what you want, the 
best and I mean the best TT receiver was the analog Omni A. Steve, N4LQ 
had a simple mod that improved the CW receive to optimum. The phase 
noise in the OmniV- OmniVI is objectionable to me. The Corsair II was 
much better, BUT the A still wins. The C is a close second, with some 
"whine" from the digial dial readout. Tough choice....73

PS Anyone have a decent OmniA for sale ???
