So many options out there...
I ended up with the Rogers Hi Fidelity integrated for way under $6K !!! It's a SET AMP, Class A, can replace between KT88 and EL34's auto bias. Low power though, like no more than 10 wpc... My other choice would have been something from Cayin or Line Magnetic but decided to go with something made in the USA. Lately, Vincent (hybrid) has been getting great reviews too. GOOD LUCK !!!
