I've got sensitive speakers,built for low output Valve Amps,but am not too keen on going the valve route.I often have short listening sessions(fitting in around the kids TV
watching),so I do'nt want to be turning the amps on and off every few minutes.How about a good Class A solid state power amp?I would like the valve warmth and rich mid range without the fuss.Too much to ask?
I thought of the Monarchy Audio 70 Pro's,Sugden Masterclass or of course the grandaddy Krell's.
What is your experience? I do'nt mind going for 2nd hand, older models,in fact most of my system is 2nd hand.
Your advise would be very welcome.

Why no mention of Rowland? The most innovative, best built, least redundant line in the world is perpetually ignored by Audiogon subscribers. Is it because you don't like the sound or because the prices are not competitive on the watt/dollar scale?
I think there is no better value out there than a used Concentra.
Any particular reason for exclusively looking for Class A solid state?

While there are alot of great Class A amps, I think you can get the same level of performance from a good Class A/B amp. I've had Class A amps before, and I'm just not comfortable with something generating that much heat in my room. You can fry an egg on some of them. More importantly, I've heard of them baking the circuit board over time and lifting the traces.

Of course, there are tons of people who've never had a problem, but why deal with the extra heat, power cost, and reliability issues if you don't have to. Nevertheless, if you want Class A suggestions, I would check out the Plinius. Also, I haven't heard it, but Bedini supposedly came out with a Class A amp that runs just warm to the touch.
According to Rowland's website, the Concentra is class A but putting that aside, I would second Labtec's question; Why be insistent on Class A?
Macrojack, the thread asked for power amplifiers not integrated amplifiers. I'm not qualified to challange Jeff Rowlands assertion that the Concentra is true Class A. Let just say it's a novel approach. With regards to why limit recommendations to Class A out put, I'm just trying to respect the question as put forward. Other wise I think Rowland is a very good suggestion.
