Integrated amp choice for JMR Offrande Supreme V2

Hello A'goners-

This is a longshot, but I'd like to know if anyone has experienced especially good synergy (magic) with a particular integrated amp driving the JMR Offrande Supreme V2.

The Offrande sensitivity is rated at 91db, at 8ohms, with a minimum of 6ohms. I'm currently driving them with my Audio Research VSI60 KT-120-based tube integrated, and the match is good, maybe not spectacular - just wondering if I'm missing out on anything.

Bob Neill of Amherst Audio (great guy), the distributor of JMR speakers recommends the Blue Circle FtTH hybrid integrated for it's combination of sweetness and clout. I don't live in the vicinity of any Blue Circle dealers, though, so I can't try before I buy. Recommendations from other dealers include the Lavardin IT, LFD NCSE II, the Ayon tube integrateds, the Mac MA2275, and the Audiomat integrateds.

Any experience shared would be greatly appreciated!

Thanks - Bob R
