Thinking of upgrading at arcam faj a22 for used peach tree audio nova 500

Sure the PEACHTREE has a lot more features and a lot more power, but I doubt that the latter is necessary nor will it provide you any meaningful step-up in performance with your NOLA BOXERs,

The NOLAs seem to be very well matched with 100 wpc ARCAM amps.(and based on the review, a host of other British  contenders)

“ …To start with, as I always do, I paired the Nolas with my tried and true Arcam A-80 amplifier. Even after all the wonderful gear that has graced my shack, I still enjoy the A-80’s affable and perfectly pleasant presentation. The Boxers took to the British kit like a born punter. The Nolas instantly made a big hit with everyone in the room, and comments such as "the ported bass really makes a difference" and "incredibly rich sounding" were bandied about by all and sundry. In this incarnation,…”

Thank you aka ca for your input.  I realize I made a mistake.  My amp is the arcam Fmj a18.  I should not rush to judge the capabilities of the boxers.  But with my setup I know the amp is my weakest link.  I really don’t want to spend more then 2500 used on my next amp.  I am just not thrilled with my sound as of now.  The peach tree was a thought but I really rather have a tube intergrated amp.  Is there any recommendations for something I will know as a major improvement?  Thanks again 

Your NOLAs are a very efficient rating of 90db. Simply piling on a larger wpc amp is a waste …big time.

It seems that they favour British amps synergy wise. The Brit offerings in your price range are mostly s/s and not tubes. A close s/s proxy to a tube amp in your price range is the SUGDEN A21 Signature that runs in pure Class A that would be a fine contender and no pretender.

I am running Nola Boxer 2's. They are currently paired with a First Watt J2. Great pairing. I also run them with an F5,another low watt class A amp,and a pair of Monarchy Audio amps,run in mono.  All sound wonderful.  Check out class A.
