VAC PA60


Hi,

does anyone know the VAC PA60 from his own experience?

I own the unit (two PA60-C + one PS90 power supply) and use it with my Paragon 12A occasionally. I find the sound rather thin and lacking in bass weight and extension, so far nothing I would describe as tube warmth. The unit has relatively new tubes (Svetlana KT88, Mullard/Brimar ECC81/83). The bias is set at 72mA for Ultraliear mode and 70mA for Triode, which I prefer cause surprisingly it sounds more full in the bass than the higher powered UL mode.

With the Paragon hooked up to my solid state Gryphon amp every lack in bass weight and extension is gone, to sound is more warm overall. I wonder that the solid state Gryphon should sound more tube like, than a VAC tube unit!?!!? By the way the speakers are Cabasse Iroise 500 with real! 91db and a normal 4ohms without any stressing low impedance dips...so nothing hard to control.

At least VAC is not known to build very thin or analytical sounding amps...?!?!?

Your comments are highly appreciated.

I used to own these amplifiers which were quite good.

However, with only one power supply I think the amps are only 45 watts. You may be clipping them, and VAC amps sound horrible clipped.
