CJ CAV 50 vs. VTL IT 85 vs. Rogue Tempest


I recently bought a pair of mini-utopias to replace my dynaudio 1.3MkII. Currently, i am looking for a substitute for my plinius 8200MkII integrated amp.

I have always used SS amps as I am bit apprehensive in the hassles of tube maintenance and hate long warm up periods. Thus, as of now, I am thinking of getting a yba passion integre for the jm labs. However, this amp is not readily available where i live (Philippines) and the distributor is in Singapore. Hence, warrantiy may become a problem.

But assuming that i would venture into integrated tube amplification, which would be the better choice?

These three products (cav 50, IT85 and Rogue Tempest) are available in my country (Philippines) and are almost priced the same.

However, I am not yet familiar with tubes... so to all previous owners of these amps which one do you think would:
a) most likely sound best with the mini-utopia;
b) be easier to maintain (i.e. biasing, tube switching);
c) have more functions (i.e. switchable to diff modes);
d) most likely become obsolete soon due to a change or upgrade by the manufacturer.

The rest of system is a MF Nuvista 3D player, analysis plus oval 9 cable, DH labs air matrix iconnect, audio
prism foundation 2 (sorry dont have any power cables as i am not really convinced by it after several demos). Room is 14wx22lx8h and music preference is jazz and vocals.

Thanks.

Between the CAV-50 and the IT-85, I'd go with the VTL based on my demo of my own MV-55 against the ST-85 (these are the non-integrated versions of the same amps). Can't comment about with your speakers though, and biasing the C-J is easier since it doesn't require a separate multimeter. One note: I'm not sure what you mean about 'warm-up' time - tube amps generally don't require as many minutes to reach their best sound as do solid-state amps. If you're talking about how quickly they make sound, the answer is about 10 seconds. They sound OK after about 30 seconds, and sound their best after about 15 - 20 minutes - quite a bit shorter than the 60 - 120 minutes required by a lot of SS amps to sound their best.
Rooze, unless you listen fairly infrequently, it's time for you to consider a tube change, at least on the power tubes. It's hard to hear the slow degradation over time, but a fresh set will often be a shocker. Allow me to suggest Svetlanas, which were a major improvement over the Sovtek/EH tubes C-J stocks in my MV-55. While you're at it, I would also switch out the 12AX7's with Yugo EI's and the 6SN7's with Chinese, since neither are too expensive, and all can be had at good prices from Tiode Electronics online, with the EL34's tested and matched. But the power tubes are the main thing - just give 'em a week to burn in, and I'll bet you'll be marveling at the difference. Just my opinion, but one based on experience...
Rooze, I've always found them to offer the best prices, and they're good to work with, if shorter than some on specific advice (C-J itself is outrageously expensive for replacement tubes). If you do the retube, let me know what you think after burn-in.
