Suggestions on Integrated Amp./Seperates to Run my Klipschorns

If your Khorns are stock, I would recommend updating / replacing the crossovers. I also recommend, damping the mid horns and tweeters, using a product such as Dynamat. There are youtube videos discussing and showing how this is done. The metal bracket used to add the rear support of the mid horn, is also very resonant, when the speaker is playing. They have great potential, and most folks on the "Gon, have never heard, a modified and updated pair, which is, ime, necessary, to take them from good, to great, and, they are. I use solid state with my Lascalas, which is better for me, than tubes. A Class A amp would be my choice, and, you do not need a preamp ( the additional gain ), unless, you do want to add some color ( Dac to amp would need to match, as far as driving voltage is concerned ). I have been listening / dealing / tweaking, with Klipsch Heritage, for many years.

I owned 1976 K Horns and used them with a Mac 2105 and a vintage Fisher tube pre, and it was great. They didn't need that power for sure but it didn't hurt. If I had them now, I would surely try a 8 watt 300b of good quality, or even a 300b push pull with double that power. Also agree with roberjerman that a good 2A3 integrated or power amp would be a great choice. 

Three times I’ve had sit downs with corner horns. All three times were Mac, MC30, 60 and MC240. It was a toss up for me, between the 30 and the 240.. My oh My.. they can light up a room.

Something about a great 6L6 valve. Tones the highs down a bit, but the BASS is just the way it should be..EL34 valves have great midbass all the way to the top. Then BRIGHT comes to mind.... I choose the 6L6 for that reason, with THAT horn. The MC240s could drive them over 100 db clear as a bell, or horn in this case.. Great speakers...I love great sounding horns....I gotta build a set..... Vintage Klipsch is like vintage Mac, just keeps going UP...

A note: I heard the old LaScala that were all tricked out with Decware M60s I think, They were 60 watt monoblocks. He used a Decware preamp too. I was VERY impressed with that set up. Visual works
of art,  just amazing.... BASS, MIDS, HIGHS.... perfect... The speaker ICs were solid core, too.
The guy made it a point to say that...SC wire, some state of the art IC.

that’s klipsch owners you’re going to see a lot of people with The same speakers and great recommendations to get the best out if 
me myself I’m using klipsch CF4 and KLF 30 with some mods from Bob Crites 

My dealer uses the Luxman CL38U C w/the matching MQ-88 amp. Plenty of power w/a smooth detailed top end. For less money he also goes w/a Prima Luna EVO 300 in Triode for a warmer sound and Ultra Linear for rock.
