Integrated Amp $1200 or less

Once had a Rega and liked it.

Had enough opinions ? Obviously, there are many good possibilities. The FRITZ speakers may perform well with tube amps but I wouldn't rule out solid state. Now here's something for thought. In as much as it's doubtful that you have access to a dealer that carries one or more of the suggested amp prospects, you might try this. SCHIIT AUDIO has amazed the audio market with some really over performing audio products including integrated amps. If memory serves, They offer, factory direct, a trial period for their products. If it doesn't "ring your bell", return it for a complete refund. A second thought on the same theme;  - - - the PS AUDIO "SPROUT". I haven't had the pleasure, but several credible reviews, pretty much rave about it's performance. And again, return it for a refund if your not happy. Both products I have mentioned have been said "to punch way above their (dollar) weight". And the best part of all, they are both well below your budget figure. 

I was earlier thinking about buying a Hegel but went another route but it could be nice brand for you to look at.

There is a Hegel H120 on Audiogon right now for about $2250 which is more than your budget but it includes a dac and a streamer which may make it worth the extra cost.

@willgolf I had the Nighthawk MKIII here with a various assortment of NOS tubes in the Preamp section and was very underwhelmed.
To my ears, in my system, I found my Hegel Rost superior in pretty much every regard. Also, my speakers fell right in the middle of the Nighthawk’s spec sheet on Raven’s website...90db. They list the Nighthawk to be used with speakers 85-95db.

I currently use a Yamamoto DAC but before I acquired that I was using the Rost as an all-in-one and I was AMAZED at how good the DAC is inside. So good in fact, that I was on the fence for months about getting a standalone DAC.

What’s also amazing, to me anyway, is the performance of its headphone amp. I was blown away with it driving my Hifiman Arya. I liked it better than my Burson Conductor V2+ so I sold the Burson.

I bought my Hegel Rost brand new, unopened from a dealer for $1,400. It retailed for $3,000 so the deals are out there. It was discontinued which is why I got the deal, but I’m just saying...

Another vote for a used Hegel. I have an H160, and am very pleased.
