Tubes cannot have frequency extension like a transistor.
ROTFLMAO... this statement is laughably false.
Had a pair of your OTL's running the top of my Vandersteen 4a's. Nice
amps, but they were NOT a neutral sounding amp and DID NOT HAVE the air
and transparency of their solid state equivalent.
I've had a good number of customers running the 4as full range that would beg to disagree with you on that point. I showed with 4as at CES one year- Richard walked into our room and complained (maybe that's not the right word- he was actually pretty happy) that we had better sound than he did. Just FWIW and that sort of thing, our amps have power bandwidth well past 100KHz; 1 watt power is flat to 200Khz and the output section by itself is good to well past 50MHz (the risetime is about 600V/uS which few transistor amps can do; the voltage amplifier input is what is bandwidth limited). So yes, tubes can have plenty of bandwidth extension like a transistor.
You're not going to find ANY Gimbaled tonearm at an affordable price that beats a VPI Unipivot.
That depends on what is meant by 'affordable'. The Triplanar uses lower friction bearings than the VPI so might be a candidate for contradicting this statement...
If you spend even more money, and the bottleneck persists, you will be really upset (smile).
This appears to be where things sit. Without knowing why a perfectly good cartridge isn't working right its a good bet that future exploits will be doomed to the same fate- those who do not learn from history etc....
