Tube amps under $7500

@mdalton 

Something tells me that's not your first time putting that formula into play. No matter, I couldn't agree more. While price (and resale price) is a consideration, it's a rather distant cousin to the priority of value. At least for me. I'm often surprised by how often people fail to make the distinction.

I would consider the Coincident 300B Power amplifier monos...single ended for efficient speakers, but with plenty of bass foundation, liquid mids and extended, soft highs.  Israel is a good guy that has been in audio for decades!  P

@hickamore Other than silver color, Circle Labs M200 could tick all the boxes if you are considering high current SS route.  It is a great looking amp though.  I believe at the price of the one currently available used, it would be difficult to beat.  This hybrid amp has tube warmth and very good SS bass paired together seamlessly.   I have the integrated version .  Very special amp.  Good tube warmth,  but still accurate and fast.  Coda may also be a good fit for you, but for me this is the only SS ( hybrid) I have heard that hasn't left me wanting for my tube amp.  Review is worth a read.  

@yoder New one to me, like so many tube amps here. Thanks. I am indeed also considering Coda and will check out this one as well before pulling the trigger.

I'm going to put in a vote for the VSi75 by ARC.  One can probably find it used for under your budget.
