Want a new amp but what to get?

For a good match, why not the Anthem STR amp? I have found that sometimes mating amp and preamp from the same company can give synergy.

Another choice of a well-built amp that will last a long time is the Bryston 4B3. I am using that with the STR preamp and think it’s a great match.

Benchmark AHB2. If you want more power you can buy another down the line and strap them. I do not own this amp but I have had them in my system and I do use Benchmark’s ADC. Benchmark is a commercial electronics manufacturer and their pricing is less abusive than Pure Audio companies. So, you get much more for the money. Their stuff is beautifully made, 1st class and surprisingly small but don’t let that fool you. The AHB2 handled my speakers, full range ESLs without any difficulty. VERY quiet, neutral, dynamic little powerhouse. The only other amp I am familiar with of the same value is the Parasound JC-1 which is no longer available new. The little amp runs circles around amps weighing and costing a lot more.
Oh, and with the money you save you can get another sub😎

At one time I was thinking of getting the STR preamp. I changed my mind when I decided to forego room correction. However, at that time I was thinking to pair the STR preamp with the CODA #8. The web site is not updated yet with the listing for this amp. I recommend searching on Audiogon for Teajay's review and feedback from users.

Whatever, you get should be complimentary to the needs of your Focal speaker. 

I owned a Benchmark AHB2 amp at one time and was considering buying it back to use with a STR preamp but the speakers I am now likely going to get did not match well with the amp. 

Thanks for the suggestions! Going to do some research on these suggestions.
