The TA-10 and TA-20 are both hybrid, but the TA-30 is an OTL (you have that big ol' power tube in addition to the preamp tubes).As far as i know the TA-30 is also a hybrid. In fact it’s wise to be satisfied with the CTH as going OTL is an endless rabbit hole
The main problem with OTL amps is that they tend to cost a lot more than hybrid ones or transistor-based amps, and they heat a lot which is not suitable for my use (I also hate the fact they they usually emit a lot of light). You also have to take care of replacing the power tube after a few years, etc. so that's really a lot more hassle, unless you go straight for a very clean and high-end amp with a four-digit price
In which case I'm a lot better off my $150 CTH
