Any one has experience with Sugden Integrated?

Looking to buy one of these class A Integrated , A21A or A21SE, will pair it with Tannoy GR Speakers , any input will be appreciated.
FYI. There are 2 Sugden amps for sale on Canuck audio mart a21a $2300 cdn and a21se sig for $2999 cdn great deals with the US dollar check them out 
I own the A21se and love it. Check out the recent Tone Publications review. The review ends this way:

“I guarantee that this is an amplifier, that once you hear it, you will never forget it. Very enthusiastically recommended, especially in a world where we mistakenly think that “high end sound” requires a six figure budget.”

I used a Sugden Masterclass SpA-4 with my Turnberry Gr and it was one of the best pairings I had. 
I have heard the "regular" Sugden A21 which I thought sounded beautiful on Devore speakers, and the Masterclass which I thought was sublime. Why aren't these spoken about more?  
One local retailer in town has Sugden as his affordable ss line.
He also carries Devore, Line Magnetic, Innous and Nagra along with
many others good brands. AZ HiFi in Phoenix if you can get here.
