Rogue Cronus Magnum II, but I have depth constraints..


Hi all -- I am getting ready to pull the trigger on a Rogue Cronus Magnum II to pair with my KEF LS50 speakers.  I've listened to a number of SS and Tube integrated amps (Hegel H90, McIntosh MA5200, McIntosh MA525, Fezz Titania, Rotel A14 to name a few) and the CM2 was the above and beyond stand-out for my ears.  I had set a $3500-ish max budget for the amp, and the price tag on the CM2 is an added bonus.

Here's the problem.  The Rogue's depth might be an issue.  I have a very well ventilated AV stand, however it has vented enclosures on front and back with an absolute max depth of 18.5 inches.  I believe the Rogue's depth with knobs and inputs is 17.5 inches (I've also seen the depth measured at 17").  Is there any way an inch of wiggle room is acceptable for long term operation?  I'm sure I can make it fit, but it will be snug.

If this won't work, one integrated amp I haven't listened to is the PrimaLuna DiaLogue.  It has a more reasonable footprint for my space.  Any opinions on how it compares sonically to the CM2 before I seek out a listen?  The main thing I've learned in this search is that I want tubes.  It's what's right for me.

I'm currently driving the LS50s with a NAD D3020 via the internal DAC (RPI3+Allo DigiOne+Volumio via Coax) and a Pro-Ject Phono Box S attached to an AT LP3 with Ortofon 2M Red.  I mix up vinyl and digital pretty evenly, with an emphasis on jazz, soul, and indie rock.  I'm satisfied with this setup, but I want to get some more power going before I upgrade the TT.  As you may be able to tell, I'm just starting to get a bit more serious about this again after many years away from audio.

Thanks all -- I've lurked this forum for a while and am constantly impressed by the quality of the advice here.

I went in the other direction.  The CMII knocked the Ayre AX-7 down to my second system.
Nice. I when up to an Ayre AX5 Twenty.  Much more refined than the Rogue. Both are excellent amps. 
After all the helpful advice, I didn't want to leave folks hanging.  I did go back for an A/B with the Rogue Cronus Magnum II and the PrimaLuna Prologue (instead of the Dialogue).  Both great sounding amps, but Benny Golson breaking in on the sax in "Moanin'" made the difference.  The PrimaLuna didn't give me the same elation that the Rogue did.

Great local shop here outside D.C. let me bring the Rogue home for a couple hours and it's going to fit great in the space (with a nice cut out in the back of the cabinet for the wires).  Headroom should be no problem as there's over 12" above it.

Ordered it a week ago.  Eagerly, eagerly awaiting its arrival.
What did you decide on?
I’ve got both a CM and a Dialogue Premium, I like the PL slightly better, but quite happy with the CM. I think the PL has a bigger and deeper soundstage, better grip on the bass,  and more detail. Both with 120 tubes, but the pre tubes are different, so…. 
Cool thing about the PL is the ability to switch between ultra linear and triode from my seat. Matched with a pair of Totem Arros, I was quite impressed with the soundstage on Roger Waters “Amused to death”.  
The CM is no slouch and it’s pretty much a coin toss. 
Just my 2¢

I got the Cronus Magnum II. I thought the Prologue was great, but I enjoyed the Rogue more when listening to my preferred music styles (jazz/acoustic). I do think female vocals were a shade better on the PrimaLuna, at least on the recordings we went through. I’d like to hear the Dialogue too, but the price difference between the DiaLogue and the CMII left some wiggle room for accessories..
