Same old same old !
Tubes VS Transistors its like comparing apples to pine apples, both have their merits and pit falls, I use an old Dyna ST-400 at 250HZ down in a biamped system for driving my EV-18's sub, the tube amps are MC-60's that are crossed over 250HZ up for mids and highs which are very sweet in this range, transistor amps make very good Low frequency amps and tube amps make wonderful mid to high frequency devices, tube amps tend to get soggy at low frequency due to the output transformer its hard to pass what is close to DC through a transformer, thats why at best 30HZ is the cut off point of MOST tube amps for the exception of OTL's transistor amps seem to screach at high frequency, mosfets has helped that some what but still the same is noticeable
Try mixing and matching with a cross over bi-amped system you may like the results.
