Mcintosh MC275 vs Marantz 8/8b

Marantz8b all the way. Less tubes in the audio path. Superb output coupling transformer. The Marantz can drive electrostatics like Quads and any speaker with a sensitivity of 88dB/1W/1meter provided you don't listen at earth shattering levels. An original 8b will require service unless it has already had it's power supply caps and the voltage doubler caps replaced.

I had the pleasure of hearing a worked over 8b today. Simply awesome sound. So rich and complete. I'm a solid state guy and it takes a bit to 'wow' me, but the 8b was 'wow' worthy. Simply exceptional.

I already use a Marantz 8b with B&W 803s, in ultra linear mode , excellent experience , really amazing
