Hi,

I need your advice on the selection of a nice power amp for bass.
Currently I enjoy 4343 in a biamp mode. For bass, I use Adcom 555, and prior to that,
used Crown DC300A-II. Comparing the two, I want to give a higher mark to Crown.
I'd like to upgrade this amp for bass sooner or later.
Could you recommend any nice power amp, modern or vintage, for the bass?
Thank you for your guidance in advance.
