Thanks for that.
Harrison not a name that comes up here in the UK, but I've found these, which are switchable 10/15/20db. Being able to do this could be useful. I have Klipsch Quartets which don't need the volume control up too far!

The other make is Rothwell which have 10 and 20db versions.

Being nearly twice the price for a fixed attenuation Rothwell, makes the Stageline ones look to be much better value.
Any comments
Thanks. The Quad II's are only 15 watts each so not overtly beefy but then Valve watts always do seem more powerful. Currently using a Luxman L30 and that's only 2 x 30 watts. Neither the Quads or the Luxman need a delicate touch on the volume control but both can supply the Quartets more than I or my neighbours need...... 8)
Yeah, you are likely in the 1-2 Watt power level for full listening level. With a 15+ Watt amp with .7V input sensitivity, you'll need a significant gain reduction from your preamp for a comfortable listening level (or pads at the input of the amps).
