Tube Amp for Magnepan 3.6 - Rogue Zeus/VTL-MB450


Hey Audiogoners,

First post to A-gon and I need your advice! I've researched this site extensively, read thousands of your threads, and purchased good product through you folks. So here goes.....

Bought a used pair of Maggie 3.6Rs -absolutely love them! [Chose over ML Odyssey, Ascent i (also liked), Maggie 1.6] They're accompanied w/Supernal tweeters and an AMC B1-20 sub. I'm upgrading my stack from ss to tubes. Caught the addiction! Having listened to tubes while auditioning e-stats/planars, I've concluded that they just make the sound more "real life" -at least for my taste (go to alot of live shows). I just love that sound!

Also picked up a used VTL 2.5 tube pre-amp along with the 3.6s. Had no prior knowledge of VTL. The 2.5 presents a beautiful large deep soundstage (3D), brings everything to life, sounds tubey -not overly tubey. I've heard some pre-amps I like better (Viva Linea), but at a much higher price point.

So, I want to upgrade two things -Amp and CD

Amp:

Having had such good experience with VTL, I'm tempted to pick up a used pair of VTL-MB450s (at half list), never having heard them. Also considering Rogue Zeus (used)-listened through modest set of electronics/speakers. The Zeus is so powerful that it actually carried the entire system. Bass is tremendous -best I've heard in a tube amp so far. Could have been a tad more articulate in the mid/highs, and didn't present a deep soundstage, but I'm tending to attribute these limitations to the electronics/speakers that accompanied the setup. My sense is that the Zeus could power my 3.6s very well, and drive them to their potential. Zeus is also very well made. Liked the warm standby switchable mode as well as built-in tube biasing. Knocks -it's So friggin' heavy (even more of a monster in real life), & pumps out a ton of heat. Definitely an Uber-amp.

Is there anyone out there in Audiogondom who has listened to both the Rogue Zeus AND the VTL-MB450, and can give me a real life comparison???.....

Other products I've auditioned ...to give a sense of my listening tastes (please DO NOT BE OFFENDED as I'm not trying to knock a brand of gear you may own; it's all good):

ASL Hurricanes - listened opposite Zeus, w/better electronics/speakers. Found them to be more articulate (tubey) in the mids (real nice), lean highs, definitely light bass (compared to Zeus).

Jolida 3000 monos - sounded decent w/3.6s. Tad syrupy. Definitely not the bass slam/quickness of Zeus. Good sound none the less.

Sim Audio Moon W-5 (I know it's ss, but comes highly recommended with the 3.6s) - listened while auditioning Metronome tube CD (w/Moon stack, Triangles). The whole setup disappointed me. The sound was flat, not dimensional. Maybe it was the setup. I'm still stumped.

Can't find Wolcotts in my area. Haven't auditioned VAC.

So, VTL-450 or Rogue Zeus? And why?

Second question, CD.

Tubes?

I really like the Shanling 200 sound, but have heard consistently horrible stories (from 3 of 4 dealers) about reliability. Heard they've addressed firmware issues, but still leary about dropping bucks on a unit with double digit failure rate.

Others...
Metronome CDv2 demo - just sounded flat an uninspiring (maybe it was the system).
Jolida 100 modified - sounded good; lively, crisp, warm but not too tubey.
AMC DB6 modified (with an AMC DAC9 modified) - decent, but not as articulate or sweet as Shanling, not as crisp as Jolida, and didn't seem all that well built. I do like the DAC9 by itself though.
Eastern Electric Mini Max -good for the money, well built, but simply can't compare to Shanling sound.
Audio Research top loader -didn't enjoy w/Krell stack
Musical Fidelity 308 -beautiful crisp highs; maybe should audition w/tube stack.
Wadia 861, McCormick ($3K) -just didn't enjoy them

So, I'm stuck. I like the Shanling sound, but not its Word Of Mouth reliability.

Any other suggestions? Next on my audition list is the Cary 308t. Remember, I'm looking for that warm, lively, beautifully finished sound -but not too analytical.

Sim Audio Moon Eclipe? Rega Jupiter? Other?

Thank you folks.

I have heard all of the players you mention. The Lector is good for the money, but for similar $$ audio aero prima will offer up 85+% the performance of the audio aero capitole mkII(which I used to own). While the Capitole MKII is hard to beat in a one box configuration(in particular for the money and what it is capable of doing) for a wee bit more the Emm labs puts it to shame and is well worth the price of admission if its with in reach. I prefer the sound of the Shanling over the cary and oracle. I have not heard about much for problems with the shanling, however for similar $ I would look more into the prima or lector. If you can squeeze a little more out of your budget Resolution Audio Opus is good, a bit more cash Audio Aero Capitole mkII and even a little more Emm Labs DCC2/CDSD combo. The lector, shanling, and capitole mkII have tube outputs the prima may, however, I am not positive.
The Bryston 4BST and SST and 7Bst sound very good as do the Rowland Concentra II. The ARC D300 is a great match also. Tubes that sound good are the EAR 509's, the Music Reference RM9 MKII and the RM200. The last are magical with that speaker. The clear, clean sound is marvelous. You are doing the right thing many don't do...using your ears and listening to all you can. Jallen
Greetings, There is no question that any Maggie is going to "come alive" with gobs of power. I have the 1.6's, and I thought I had good sound running a Threshold T-50 (50w class A). Man was I wrong! Lately I bought a 5 channel Outlaw at 200wpc. For fun, I bi-amped each speaker, for a total of 800w on the 1.6s. I was astonished, flabbergasted, etc. And the sound became much more tube-like, smooth,etc.
Also, you may want to consider the impact of interconnects. I have switched to the new Audioquest dbs line, and the Maggies have taken another leap in sound reproduction.
Frankly, I was going to consider tube amps in the future, but all the postings are reinforcing my concern; any kind of economical tube amp won't cut it for driving Maggies.
I would suggest you do a demo at home with at least 1000w of power running into your mains prior to making a purchase of tube amps. You might possibly obtain best results bi-amping at about 300wpc.

have fun; aren't these the best kinds of problems to have?
For a CD player try a used Musical Fidelity NuVista 3D ($3700), a Musical Fidelity TriVista ($6,500), or a Krell SACD standard ($4,000).

To add slam to the Maggies, try a pair of Vandersteen 2wq subwoofers or a pair of Cambridge Soundworks Newton P-1000s. These subs are very fast, cheap, and blend very well.

I would choose the VTL MB-450. It has enough power. Call Stereo Unlimited in Walnut Creek, CA to discuss that combination. They sell Maggies and VTL.

How did you like the sound of the Jolida JD3000A? How was the build quality?
