Amp for SF Amati Homage? Rogue Zeus or 180, Jadis Defy 7, Quicksilver 88 or 90 or M-135

I need an amp for recently acquired Sonus Faber Amati Homage. Their impedance drops in the bass and treble, and the treble dip does not work with my Vac Ren 30/30 signature. Hate to part with the beautiful Vac but I must. After I noticed the treble problem (shrill shouting from 2500-4000 hz) I was told Amatis have a natural peak around 3k hz. This is likely exacerbated by the impedance issue and relatively low amp power.

I am looking for a tube amp (please no solid state recommendations) that can handle relatively low impedance swings... Not too extreme like planers, but below 4 ohms. I have a bit of an allergy to brightness and etch and am willing to trade off ultimate extension and treble detail to avoid etch or brightness. I listen to jazz, blues, classical and some older rock. I do have a lot of recordings that are not perfect so I am NOT looking for perfect "neutrality" but rather a slightly warm top end and a rich, full midrange. Bass is not my top priority. My system is a Koetsu Rosewood Signature, Sota Star Sapphire, EAR 834p phono, Thor Ta-1000 pre, and the Amatis. Cabling is all cardas golden cross (warmer stuff) ;)  I listen to mostly vinyl.

My budget is under $4k used, inclusive of tubes. Could anyone give opinions on my shortlist, especially relative to one another?
- Jadis Defy 7
- Rogue Zeus or 180
- Quicksilver 88, 90 or M-135

Thank you for thoughts!

So you are looking for a tube integrated amp? Well.... I was going to recommend you the Audio Research Reference series but with your under $4k budget used I'm not sure if even a used ARC Ref series integrated can be had unless if it's a much older model. 
Or try a used McIntosh tube or SS integrated amps. Even McOntosh SS amps are warm like tubes.

No sorry... I am looking for a tube power amp, not an integrated.

 ARC Ref 110 amplifier. You can run any 6550 variation including  KT88 and KT120 tubes. It has a tube hours meter which lets you keep track of how many hours are on your tubes. It is a very nice holographic sounding amp.

+1 on the ARC Ref 110 amp. Sorry I thought you were looking for an integrated amp. Yes the ARC and McIntosh tube or SS will pair really well with your speakers. Like I said earlier that even McIntosh SS amps will have a warm tubey sound. See if you can find a used MC302 or MC452. Not sure what they are selling in used markets cause used Mac gears sell pretty high. Mac has very good resale values.

If you can not stretch your budget, then above will be pretty good choice.

Your speaker has a sensitivity of 92db/w.
