Help with Hi Power Tube Amp Selection

I will have to correct the previous post VTL amplifiers have longer tube lifes than many others due to the lower bias current being sent to the tubes than other companies typically do which increases their longevity. typically approximately 3000 hours for a set of tubes with VTL's

the Wolcott is pretty particular about the cables you use with it especially in the midrange you don't want cables which are thin or lacking body in the mids. The VTL 450 has a bit more mid range body than the Wolcott and cable matching isn't quite as critical. The difference in the two amplifiers really isn't very much different especially if the 450 is in triode. It's like which brand of chocolate ice cream you purchase? Yes their are differences but they are slight. The Wolcott definitely has better bass control and power but it's not a big difference. I preferred the 450 signature in triode. What can I say if the mid range isn't exactly correct I'm not happy. I can say the 750 reference amplifiers is better than either of those above at least in my system. Neither one of those above actually has enough upper bass powers and definition something the 750 has in spades.I know now I had a cable compatibility problem with the Wolcott which I didn't have funds to correct it with at the time. All 3 above are very good amplifiers.
