Jolida 502b, Manley Stingray & VTL- I85 compare ?


I would like to find out if anyone can compare these three
integrated's on my short list. I can not listen for myself.
I want to try tubes in place of the SS that I have now.
I am using JM Labs Electra 926's with an Audio Aero Prima
CD player. I would like info on the sound as well as the
quality of the units. My room is 13'x 26'(@2700 cubic feet). I listen to classic rock, rock and contemporary blues . It is 'rock' so I like it somewhat loud!
Is the Jolida mod by Underwood a significant improvement
over stock ? I can get a used stock unit for $700 and a new
modded unit for $1549 with warranty.
Thank you in advance.

Boa2; your suggestion of the Audio Aero sounds intriuging. I wonder if it's 40 watts is enough to drive
my big floorstanders ? The sensitivity is 91 or 92. I have been told that I should have at least 100, high current,
watts to drive the Electra's.
All of the answers have been informing ! Keep'em coming.
Thank you.
Saki70,

I've been using the Hybrid Amp with 89db speakers, and I can't turn the amp past 10 o'clock--and that's when listening to Tool. You would have ample power, I'm sure.
It makes such a great combo with the Prima CDP.

The newest Prima Hybrid amp can be found (check or place a wanted on www.canuckaudiomart.com) for the $1300 range, and is 50W. It also has remote control, but does not have the sub/pre out like the older version.

Finally, a NEW NEW version is coming out early next year--100W. 40W has been plenty for us, and would fill a room much bigger than ours 14' x 14'.
Saki70, good to hear that we didn't lead your thread astray too much.

By the way: I have seen the older(?) version of the Audio Aero HyBrid here on audiogon for as little as $750. For some reason they seem to be selling fairly slow. Although that should change if more people are reading your (Boa2) enthusiastic threads here on Audiogon. Are there any differences to the newer version?

Howard (Boa 2), thanks for the suggestions for the tubes. I have been hoping somebody would suggest some tube rolling on my virtual systems page. I noticed a big change in going to the Mullard for the 12AT7. More involving (hard to believe but true), better timing and rhythm and even better smoother midrange with out softening the bass and the highs too much. The gold pin EH 12AX7 brough in a lot more detail but sounded a little more sterile compared to the stock Jolida tubes. Only problem is that the 12AX7 NOS are usually much more expensive than the 12AT7. Well maybe sometime later.
I know this isn't on your "short list" but do yourself a favor and put ROGUE AUDIO Tempest (integrated) on that list. Actually, since your room is a little big you might want to try the Tempest MAGNUM. It is 90WPC compared to the 60WPC of the "standard" tempest. Which is what I own. I too had a SS and wanted to change to tubes so I purchased the Tempest with NO regrets. The tempest is heavy and built like a tank, and makes instuments and vocals come ALIVE. The second big selling point for me was that it is switchable from pentode to triode mode which gives you 2 different types of tube sound so you can have some variety. Just my .02 cents. Good Luck.
