Rowland preamps??????

Trank, Capri is the current production model. . . which is the one I use in my own system. Capri is said to be more extended detailed, and linear than prior JRDG pres. Whether or not it yields less or greater musical 'magic' than older models, is entirely a matter of personal preference. E.G. I prefer it over my own ARC Ref 3 because of its very linearity, extension, and control over the entire frequency range. If you valued slight euphony over linearity, you may enjoy older JRDG linestages over Capri. . . if your musical taste were similar to mine instead, Capri may very well be the ticket.
BTW, I also find the JRDG naming scheme for pres absolutely maddening. G.

By coincidence, I still have also an ARC LS2B, which I used for 10 years before getting the ARC Ref 3, and then the Capri after that. . . The LS2B is the most 'golden' sounding of the group. . . the Ref 3 is in the middle. . . and the Capri the most neutral. . . it all depends on your prefs. G.

Ferrari, have you ever heard the Coherence II? and if you have, could you comment on the differences between the 2 versions? G.

Trank, VK52SE is the only BAT linestage I am familiar with. It sounded to me on the more classic side of tube sound, with bass extension that was warmer and a little less defined than Ref 3, and with treble that would get stressed on orchestral fff. Yet, an incredibly captivating sound in its own right. . . it is really a matter of what one prefers. . .'Romantic' or 'neutral'. . . there is no right nor wrong. My preference is for neutrality with 'heart', hence my happiness with Capri. You are right about Capris having disappeared on Agon. . . or almost. . . there is one being offered in combination with 201 monos. . perhaps you can persuade the seller to let go of Capri alone. . . but I am positive that within a couple of weeks you will see a Capri or 2 for sale once again.
