best inexpensive tube integrated

You may want to consider another approach. I have a Sophia Electric KT and picked up a KingRex T20 and Power unit as a back up. Can be had new for under $600 new. Audiomagus is great to deal with and I think they offer a 30 home trial.
Just a thought. Great review on 6moons. To my ears it sounds pretty amajing.

I would look for something:
newish but used
that self-biases so you won't have to mess with the tubes
that uses KT-88 output tubes with Klipsch

I've done the EL34 & EL84 route and I think the Heresy is a little bass-shy so the KT-88 would be my first choice for more robust bass.
For $700 you might want to even consider looking at a cheaper integrated that might use 34's or 84's and think about adding a small $300 sub into the mix. Just be sure the integrated has either a sub out or 2 outs.

Visit upscaleaudio.com and look under the demo and used items. Sometimes there are some great deals there on primaluna and others that were acquired in trades, etc.

Try Glow amp one.I bought one they sell for $488 brand new! 5 watts of pentode tube,alps,go to Glow amps and you will find it,30 day money back ,Nick
