almarg FWIW I suspect that the solid state Pass XA25 I use would be fine in that regard
lordrootman OP
@almarg thanks you’re exactly right is rated 102dB
I will check pass lab out
I would also check out for "value" the Schiit Aegir 20w of Class-A which Stereophile measured at 28w, "low noise" and also far cheaper than the Pass would be. https://www.schiit.com/products/aegir and you don’t like it within 15 days you can send it back
I was pleasantly surprised by the Schiit Aegir’s measured performance. It is a well-engineered amplifier at an affordable price.—John Atkinson
And because your KLF30’s are bi-ampable, you could bi-amp them with two Schiit Aegirs in vertical-biamping.

Or one Schiit Aegir for the mids and highs and a Schiit Vidar for the bass horizontally bi-amped. (may need a Schiit Sys to even out the gain)
