Thanks for your advice, Bob_bundus.
I have read several rave postings about the A-30 or the E-530 for K-horns as well as less efficient speakers. My musical preferences lean towards rock, so I'm a big fan of dynamics. Since you get quite a lot of warmth from the Accuphase class AB amps as well, on top of the dynamics, perhaps they would be a better choice than the pure class A designs. Then again, with a sensitivity of 104 dB, one rarely puts more than a watt into the speakers. One should think that the A-30 was enough... And since the output stage of such an amp is constantly driven, it should be faster than a class AB design. If only one could try them out in my system...
By the way, are you sure that the P-450 uses MOS-FET transistors in the ouput stage? I thought it was a bipolar design.
