What is the best solid state amplifier you have ever heard?

It took a long time for a mention of Levinson ML-2's and I agree with jdl57 after enjoying  them for quite a long time. Also I still have one the often mentioned BEL-1001 and even though played on very different set ups, I always felt that both models were cut from a very similar cloth.

Everyone please excuse this side track, but my BEL 1001 could use a tune-up. If someone knows how to service it properly please PM me.

Thanks,

@kaufman I have heard of Brooks Berdan, but was not aware that their technicians were that familiar with the BEL 1001. I will explore my options with them.
Thank you for the tip.
