I now have a classic, vintage Cyrus 1 amplifier with PSX power supply on loan. Or rather to help my friend spray it black. He borrows my Topping E30 DAC, which he might buy. I am thinking of buying the SMSL D-6 DAC because it has balanced outputs with 4 Vrms out which I need for my power amps (SELA and Fostex 600).
Back to Cyrus 1. Why not. It works well.
Guessing around 70-80 watts with the PSX power supply. As usual I hear no difference between this amp power supply combo vs my other amplifiers. With 90 dB sensitive speakers and the fact that I rarely play louder than 65 dB in the apartment, I don't need many watts.
BUT one thing that annoys me is the hopeless placement of the speaker connectors. Partly because they are too close and partly because the power cable between the PSX power supply and Cyrus 1 goes over the speaker connectors. See the last attached picture, there you see the hopeless solution. What was Cyrus thinking in that case?
Traditionally budget amplification was considered to have “budget sound”. The appearance of the Cyrus One in 1984 upset this established norm and revolutionised the audio industry. It demonstrated unequivocally, that an audiophile integrated amplifier was well within the grasp of the music...

Edit:
That didn't sound good: "Freq Resp – -3 dB". What that means in practice? I do not know.
