The midrange of this amplifier is fantastic and the treble is very sweet. So far I have found the sound of KT88's to be the best to my ears. Effortless and relaxed sounding. Just a superb system at the moment. I also find the superlinear mode to jive better with my speakers.
Price point makes it a true bargain in an overpriced arena.
Due to the many options available, these amps are again worth every dime spent for the musical experience. I opted to install kimber wiring, additional supply caps, coupling caps, switching and front end dc filament supply. I truly like the result and will compare to the best at any price on the market. It has the best of the old Marantz model nine amplifier design in the front end, more detail and better bass response. I like the KT-88's for the outputs, 6CG7 current source, and the 6922 input driver stages.
