Jonathan, in reguards to speakers, I am using a pair of CC34s and the Proac D18 which presents a very easy 8 ohm load at 87db, would this make the tubes run a lot harder and hotter than say a 10 ohm load or would I need to go to something much more efficent and even higher impedence. One of the things I have wondered is the tubes are biased at 60 mAs and taking to tube techs they feel its running at the edge even for a really well built Mullard .Also looking at Mullards spec sheet it seems to confirm the techs views.
Thank you for your time,
Ken
