Jeff Rowland Synergy IIi versus Capri and Corus?


I currently have a Jeff Rowland Synergy IIi Preamp. I was wondering how it compares to the newer Capri and Corus Preamp.

Any thoughts on whether it is worthwhile to save up money to upgrade to either of these units...? Some have claimed that the relatively inexpensive Capri has bested preamps 2 or 3 times more expensive... Tks!

Sorry for the late reply.
I use Furutech Evolution II between CDP to Pre, Cardas Golden reference interconnect between pre and pow amp. Van Del Hul Jade speaker cable.
I love Cardas Golden reference interconnect, but have not listened to their higher range model yet.
However, my friend just told me Transparent Ultra interconnect is very much better than the Cardas Golden reference in term of Soundstage, tone , details etc but of course this is unfair comparision because Ultra is many time more expensive than Golden reference. Any user feedback ?
Regarding MBL gear, I listen to their reference line model 6010D pre combined with 9008A and also their Nova line, 5011 pre combined with 8011M pow amp driving MBL speaker 101 and 116 respectively.
The reference line is analytical, detailed , clean and more towards HIFI sound, less emotion and soul than the Nova line combination. The latter has more warm, relax , certain degree of colour(tube like sound without the much high degree of distorton of tube gear) and forgiving, compared with former.
In my another system, I own MBL 9006 match with Accuphase 2400 Pre amp, Esoteric P05 and D05, and Dynaudio C4 , it strike the balance of both world. Of course, this is only my personal experience. There is no right or wrong, good or lousy , is only the individual taste. Regards.
Unfortunately, not yet...

I've had to re-prioritize my funds. Given the economy, unfortunately, it may be a while for me to save up for a new Rowland pre-amp or amp. I'm leaning towards the amp side first.

It is a real bummer.
My only hope is a killer deal on Audiogon!
