The phi is not as power hungry as you think. Are you mostly worried about power requirement or synergy?
mulder01, how is it going with your system now, are you still considering selling it? I was hoping you changed your mind.
I seem to have got in deeper into Headphones. After my Stax 009 and 007 sale and the Carbon amp, I bought the LCD4s, then the V281.
I heard the Malvalve head amp at Munich hifi show this year, and it was magical, beyond what I have heard on any SS amps to date. This got me thinking.
I have got the
Aries Cerat Genus coming in. It is an integrated SET with 25 watts using big bottle tubes. Besides speaker use, it also has an excellent headphone output for both high and low impedance headphones driven by the powerful output tubes.
I was curious about the Viva Egoista for a while, wanting an ultimate tube amp for headphone use. I now I am thinking the Genus could be my end game headphone amplifier. I have heard it on speakers and it was fabulous, incredibly liquid with classic SET midrange magic, smooth treble and superb bass control and dynamics. Best I have heard in a tube amplifier to date. It is 15K euros, so an investment, but has the dual purpose of a high end integrated speaker amplifier as well as a headphone amplifier. I am told it can power any headphone. The amplifier is a big beast and weights in at 67 kilos.
I'll report back here with my findings. Anyone in Spain who wants to hear it please PM me. I am the official distributor for Aries Cerat in Spain now, so I can demo any of their products and provide local support.
