I've never tried tube amps with my Magnepans but will say that you need a lot of solid-state power, if you're going to listen above 70db. I'd recommend something like the Sanders Magtech, which does 900 into 4 ohms.
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 :)
