What integrated would you recommend for summer amp?

No doubt in my mind I would take that Thousand & get a Quad Vena 2...

AC to cool a room is around 18,000 BTUs. The Prima Luna puts out about 400 BTUs. It only seems like a lot of heat because its concentrated in so small a space. But really its beyond insignificant. Once again science liberates from the chains of wokeness freeing you to enjoy your tube amp. 

Speaking of freedom, your $1k together with selling the PL could get you out of Made in China and into a sweet Made in the USA Raven Blackhawk. That would sound better too.

Agree with MC. I’m as green as I can be but you’re not playing a zero sum game here. Let the AC eat the heat but mow your yard less or hold off on flushing every pee etc.

@millercarbon Is the Internet big enough to contain you when you get the Raven and the Moabs? ;-)

I went through this exercise not too long ago in my computer room.  I have a ductless split A/C unit in my house, but this room doesn't get a lot of flow from it and with my computer, all the attached hard drives, and my ARC Vsi55, it would get pretty warm in this room during the summer. 

I bought a second hand Vincent SV 237 for just a little over $1K and moved the Vsi55 into my office, which is bigger and stays cooler. 

With the stock tube, it had a little bit of an "edge", but the preamp section seems pretty responsive to tube rolling and I replaced the stock tube with a Tung-Sol 12AX7A and the stock 6N1P-EV tubes with Voskhod 6N1P tubes and it sounds fantastic with my Harbeth P3ESR speakers.  Very detailed, but "smoother" without that bit of edginess it had with the stock tubes.  It has more than enough power to make your Fortes really sing.  

Having said all that, in my limited listening experience at a dealer showroom, the Primaluna gear seems to match up really well with Klipsch speakers.  I think it's a little "euphonic" and am not sure I could live with it long term, but it is seductive.  If that's one of the things you love about your system, you will probably loose that with most SS options.  

+1 with MC, I have the same Primaluna Dialogue HP integrated in my bedroom and even though it does get warm it's not enough to heat up your room so that your AC would have to work extra to cool off the whole house.As for the Raven integrated I would go with the Osprey MK3 instead of the Raven Blackhawk MK3, if that was the route you wanted to go in.
