Iagree with the above...not technically minded but if it sounds good..you are all set....the only way to hear a difference is to try another preamp like a Mac c46 etc.
Are the MF308 and MC402 matching together ?
I got the Pre-amp Musical Fidelity 308CR and power-amp Mcintosh MC402. They sound great so far. Suddently I just read about the preamp - poweramp mismatch and just wonder are they perfect matching ? Cos I don't have a change to have another pre-am or power amp to compare... The preamp MF308 has specification as follow :
Voltage RMS, maximum > 30 Volts
Power maximum > 5 Watts
Peak-to-peak output current 0.5 Amps
Impedence 50 Ohms
Frequency response 20Hz to 20kHz ±0dB. 10Hz to 100kHz +0, -1.5dB.
LINE OUTPUTS
Total harmonic distortion + noise, 20Hz to 20kHz > 0.0035%
(5 Volts output, maximum volume).
Signal / noise reference 1 volt RMS output 104dB ('A'-weighted, at half volume)
Input sensitivity for 1 Volt RMS output 240mV
Input impedence 47k Ohms
Gain at maximum volume 12.5dB (4.2 times)
Overload margin 31dB
Channel separation > 88dB typical at 1kHz, maximum volume
PHONO INPUT
Frequency response reference IEC RIAA See graph below.
Signal / noise reference 1 Volt RMS output > 95dB Moving Magnet ('A'-weighted, at half volume).
> 85dB Moving Coil ('A'-weighted, at half volume)
Input sensitivity for 1 Volt RMS output 2.5mV Moving Magnet.
350µV Moving Coil.
Input impedence 47k Ohms
Overload margin 31dB
The Mcintosh MC402's specification :
Power Output 8 ohms 400 w @ 8 ohms
Power Output 4 ohms 400 w @ 4 ohms
Power Output 2 ohms 400 w @ 2 ohms
Power Bandwidth 20 Hz to 20 KHz
Total Harmonic Distortion 0.005 %
Intermodulation Distortion 0.005 %
Dynamic Headroom 2.1 dB
Frequency Response 20 Hz to 20 KHz +0.0 dB / -0.25 dB
Input Sensitivity 4.0 v
Signal to Noise Ratio 115 dB
Damping Factor 100 @ 4 ohms
Input Impedence 20 KHz
Power Requirements 120 v 10 A
Warranty (parts) 36 month(s)
Warranty (labor) 36 month(s)
Dimensions 24 cm. H x 44.5 cm. W x 51 cm. D
Weight 50.1 kg.
How can I know they are perfect match ? Or should I change the pre-amp to ultima the sound of MC402 ? Appreciate your idea. Thanks
