Hi folks.
I recently tried replacing my Arcam A38 preamp and Arcam D33 DAC with a Yamaha RXA-1060 as a preamp for music and home theatre duties. The plan was to use my 3 Arcam P1 Monoblock Amps and connect them to drive the front 3 Channels of the Yamaha. I have been using an Arcam A38 as the preamp for music and use its BYPASS mode for passing home theatre duties to the Yamaha. The plan was to retire the Arcam A38 and Arcam D33 DAC to a different setup. Hence, your input would be appreciated....
I believe I'm experiencing a symptom of Yamaha not having enough voltage gain to drive my Arcam P1 Monoblock Amps. I recall reading on Audioholics that if you are using external amplification, look for powers that have high voltage gain of 29 dB or higher.
The Arcam P1 allows for the selection of two gain settings these are 28.3 for “THX” and 37.5 for the Arcam "house" setting. Neither setting really seems to allow the Yamaha to work well in this setup. I need to turn up the master volume on the Yamaha a good ways to get any volume. You can note in the iOS app screen grab, that there is a red warning when I turn it up.
The specs on the Arcam P1 amp is as follows:
Frequency response. 8-ohm load
Input set to 1v rms
20Hz – 20kHz = +/- 0.5 dB.
Distortion. THD+N 0dBR 4-ohm load.
Input set to 1v rms.
20Hz – 20Khz = <0.02%
Power amplifier input Nominal sensitivity: 906mV (Arcam gain)
Input impedance: 22kΩ
Gain: 31.5dB (Arcam gain)
Is it safe to assume the Yamaha will not mate correctly with the Arcam P1's?
Any assistance you could provide, would be greatly appreciated!
