Power amp for Audio Research SP16L pre-amp

Oops, I apologize! I'm relatively new to Agon and forgot that I should not be directing attention away from the issue that started this thread, but should instead start a new one to get responses to my question.

Dodgealum, I just found your post and am curious -why did you replace your 100.2? I've been looking for an amp to go with my AR LS 16MkII and was told the 100.2 is more musical than the 150.2. Would appreciate input from other Agon folks who are familiar with both amps.

Dodgealum, thanks for your response. I did find it helpful. There is sufficient ventilation for the 100.2. However, it is so hard to find these days that I might opt for something else. Good to know that you are satisfied with the 150.2. I want to replace a Rotel RB 1080. The Rotel has been a real workhorse. Never gives me any problems at all. I just believe there are better sounding amps out there. Also, the Rotel does not do well when played at low volume levels. I do want an amp that is similar to the Rotel in terms of physical footprint, weight, and having balanced inputs.
