Magnepans

I'm kinda new to the plannar/magnepan world, but I am really interested in trying out a pair after all the reviews I've been reading. From what I understand these speakers are quite power hungry. What is the minimum I need to properly drive these? 
I currently have a VAC Avatar integrated tube amp. These are the stats:
Type: Integrated vacuum tube amplifier with MM phono stage and home theater (direct power amplifier) mode.
Tube Complement: two 12AX7 low noise (phono), two 12AX7 (line stage), three 12AU7/6189A (power amplifier), and four EL34 (power amplifier)
Options: Remote control for volume (motorized direct control) & mute
Power amplifier ("Home Theater" direct mode):
Output matching: 4 or 8 ohms nominal
Power output: 60 watts/channel ultra-linear; 27 watts/channel triode
Frequency response: 9 Hz - 35 kHz +0 / -0.5 dB, 3 Hz - 71 kHz +0 / -3.0 dB
Power bandwidth: 11 Hz - 63 kHz + 0 / -3.0 db ref. 50 watts
Gain: 25 dB ultra-linear; 23 dB triode
Residual noise: 1.5 mv at 8 ohm output
Channel separation: -72 dB @ 1 kHz; -60 dB @ 10 kHz
Line stage preamplifier:
Gain: 24 dB
Maximum input signal: Infinite (attenuation precedes line stage)
Noise contribution: Approx. 0.1 mv at power amplifier output 
THD contribution: Approx. 0.04% 
Tape output: Unity gain from selector, non-inverting 
Phono stage preamplifier: 
Gain: 37 dB (measured at tape output)
MC phono stage in place of the MM optional 
Residual noise: 3 mv at output (S/N ratio approx. 69 dB) 
Overload: 117 mv @ 1 kHz = 8 volts RMS output, 460 mv @ 10 kHz 
Frequency response: RIAA +/- 0.25 dB 
Notes: Does not invert absolute phase. 

Anyone know if these will do or if I'll have to upgrade? Love the tube sound . . . will I need to go solid state for Maggies? Thanks for putting up with the noobie question :)

OK, last follow-up, I promise :)
Anyone here very knowledgeable about Magnepan mods? I've been reading through a LOT of material out there and seen some people invest in upgraded crossover boxes (though not sure those are meant for all Maggie models?) and others invest in fuse bypass. 
Is there any mod that I absolutely should invest in? Any that really make a big difference in these speakers? Thanks!!!

natureboy,

     Can you give us a rough estimate of what you're willing to budget for:

1. Magnepans( 2.5R, 1.7i, 3.7 or 3.7i)

2. Speaker cables

3. Possible mods to speakers

     Just a range you're willing to pay for each is sufficient.

Thanks,
  Tim

Maybe a bit late to chime in but for what it's worth - as I do currently have a pair of Maggie 1.7s and am driving with a Rouge Cronus Mag. II integrated tube amp rated at 100W pr. channel. My listening are is about 375 Sq. ft. The 100W Rouge does a very nice job driving the 1.7s at any volume I care to listen to. The stage is very deep, wide and detailed. Not sure if 100W would be quite enough on the 3.7is but does a very nice job on the 1.7s. I think your 60W VAC would do a very nice job on the 2.5 or the 1.7 Maggies but may need more if you ever decided to go with the 3.7is.

     jhills,
     Very good useful info on your Rogue Cronus Magnum II tube integrated working so well on your 1.7s. It would probably drive the 1.7is equally well.  
    The issue becomes whether natureboy's budget is sufficient to cover the cost for the 1.7i speakers($2,000/pr.)  and Rogue Cronus Magnum 2 integrated 100 watt tube amp ($2,500) for a total of $4,500.  I find it strange and perplexing that he has demonstrated such a reluctance to reveal any budgetary info and which Magnepans (2.5R, 1.7, 1.7i, 3.7 or 3.7i) he's currently  leaning towards.  This is all required info that needs to be considered prior to any of us offering much meaningful advise to him. 
    
     With a total lack of even a rough approximation of  budgetarynumbers  coming forth from the natureboy,  I doubt we can offer him much useful advise.

      I've decided to match my level of concern to his,
                                Tim

Yes, no budgets ever shared......but based on him originally looking at a pair of 2.5s and nothing else, I would suppose his original budget was no more than a 2 or 3 hundred.......now.....who knows....noone's talkin....


The thread primarily serves future browsers as a discussion of tube vs ss for magnepan.....
