Pre and Amp Suggestions


Given the way these things go, I’m almost afraid to ask this question but here goes: I’m finally at a place where my front-end and speakers are at “destination” level-at least for me....for now.  My question is where and what to upgrade between these two extremes. The speakers in question are Revel Studio 2s which I love, and the front-end dac/streamer is the Lumin T1 ruining Roon. The Lumin feeds into an analogue bypass section (no digital conversion) of an Anthem AVM60 going in turn to two 200 watt mono channels of a Sherbourn 7300. In trying to answer my question, I would appreciate keeping to the following parameters:

-no suggestions of other speakers or front end gear, I’m in a good place where I am right now.
-no suggestions of power conditioners, cables etc. Let’s just stick to the gear.

Just looking for pre and amp recommendations (or really good SS integrated amps). The sound right now is quite neutral, but perhaps a little lean but very revealing. I’m not looking to drastically alter the sound or play louder, just looking for more of the “good stuff”, resolution, staging etc. Might consider a tube pre or hybrid but really have no interest in an all tube power amp or massive class A space heater anymore. Ok let the games begin!

Thanks Atmosphere, I am already a balanced practitioner. Much prefer gear that is truly differential. Not sure why you say the ARC is not balanced, the LS25 and VT100 is used to own definitely were. Though I do agree they were on the bleached side of neutral considering they were tube units. I think the pre was mostly to blame for that though with the 6h30 tubeset.

What I was saying is that although the ARC stuff is balanced, it does not support the balanced standard.

An example of how this is so is in a balanced line, the signal occurs with respect to its opposite, IOW the signal is the non-inverted and inverted aspects together, with ground being ignored. The ARC preamps do not ignore ground- each signal occurs with respect to ground rather than its opposite. The makes the preamp unable to control problems in the interconnect cable, meaning you have to audition the cable with the preamp, obviating some of the advantages of going balanced.
I.......did not know that. Thanks for the clarification Atmosphere. I learn something new every day. Cheers
I have to agree about the PSAudio BHK line of products. Amazing sound and relatively affordable for the quality they provide. 
I haven't heard everything out there, but I am quite pleased with the combo of a McIntosh tube/hybrid preamp and my Odyssey Audio Kismet amp.  Should be right aroud your budget, especially if you go to Audio Classics for a used but newer McIntosh preamp (like a C220 or C2300).  Roll the tubes to Gold Lions or Mullards and you are good to go.  Tons of flexibility, and the combo should give you warm, detailed, spacious and dynamic sound.  YMMV, of course.
