Rockport Avior vs. Marten Coltrane vs. Kharma Midi

Thanks for a good post! I am an Avior owner, still looking for direction in choosing electronics. I started with my 20+ y/o BAT preamp and Rowland 8T, which couldn't provide enough weight at the bottom and effaced much of what is so desirable of transients, yet offered a lovely midrange. I swapped it toward a Dan D'Agostino integrated- bass and transient/ attack problems solved! A bit warm but still lacking the emotion of the BAT/ Rowland combo. I would be grateful for your current opinion on how to get it all? Budget is whatever I can get for the Dan D'A, probably close to the $24k I paid for it. Best!

Groundhog Day??? Echo what Philb said.

As an Avior owner I agree with Phil. A tube pre is a good place to start. You can get a lot of mileage from 24k if you look at some of the gear on Agon. I recommend a ARC pre or better still a CJ GAT. I have not compared the 5SE to the GAT but reviews suggest that the latter is miles ahead. A good unit on Agon is approx 11k or so. If you prefer a tube amp , my recommendation, a CJ 125 or 140 should be doable within 10k. Don't mix and match ARC and CJ. As a longtime CJ owner my loyalty is to the latter.
A tube pre and SS amp is great in theory but unless you get to hear the combo first hand you should be wary.
All the best
