I have a vintage Yamaha amp - CA-2010 - from 1977. Had it refurbished & it’s driving a much easier load (Tannoy DMT10 Mk2 speakers) & like you I really like its natural sound. I don’t think i’m giving this amp up any time soon.
Magneplanars are a much tougher load - they like very high current amps - and I know that my CA-2010 is not up to that task.
The MX-2000 is spec’d at 130W/8 Ohms & 180W/4 Ohms & from one seller I got the following specs:
•Minimum RMS Output Power per Channel 20Hz 20 kHz
•0.005% THD, 8 ohms 130W +130W
•0.005% THD, 6 ohms 150W + 150W
•0.01% THD, 4 ohms 180W + 180Ws
•Dynamic Power per channel (IHF) 1 khz:
•8 ohms 180W; 6 ohms 240W; 4 ohms 340W; 2 ohms 490W; 1 ohm 600W
•Frequency Response 20Hz 20kHz, MAIN IN +0, -0.3dB
•Total Harmonic Distortion (20Hz 20kHz)
•MAIN IN TO SP OUT, 130W, 8 ohms 0.005% Signal to Noise Ration (IHF-A-Network)
•MAIN IN (Shorted) 126dB
it appears that it would be sufficient for the Magneplanars.
Apparently the MX-2000 is a scaled down version of the legendary MX-10000 which was capable of 1200W/1 ohms & costed $11000 when new. wow!
I think you have one serious amp there in the MX-2000. Don’t let it go...
