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!

 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.

The only thing I worry about with ARC or BAT is the possibility that the top early won't be warm enough. I really don't like amps that are referred to as neutral or detailed, in the typical HiFi vernacular. And i have a long-held prejudice against ARC that they tend to be a little dry. I like weighty, liquid mids and treble that doesn't hurt, even with mediocre recordings. Of course I want to get the most detail and extension I can, without crossing that magical line!

Given above, do you still think the BAT or ARC are recommended?
