Thanks that’s very helpful in understanding what is going on.
Does the pre increase the voltage as you turn the volume up to the 606?
Also does increased voltage into the 606 lead to increasing the wattage?
If the 606 is 140w, is that continuous or does it increase according to the pre volume?
Thanks

Lee,
The sound level meter I used was bought from Maplin. It belonged to a friend of mine, and I borrowed it out of curiosity. Can't comment on the accuracy (the meter was not expensive), however it was 'interesting' to see just how uneven the response of my speakers/room was.

I was also going to mention that I had a Maplin one, fairly cheap but quite heavy, and criticised by Alan Shaw for being cheap.
Actually I have been impressed with mine but I have not compared it with a serious one.
It cost about £30, and was on offer for £15 when introduced.
Instinctually I feel it to be quite good.

I can only speak from my own experience but back in 2009 I had a Croft pre/power combination and used Golden Jacks attenuators to over come the ridiculous over sensitivity of the amps. As a by product I also noticed a marked improvement in sound quality.
My limited experience in using attenuators to tame the 3.4 V output of my CDP into my valved pre is that the less attenuation you use (at the pre. end in my case), the less it affects s.q.
Despite learned technician types on another forum recommending -20 dB attenuation or more, I tried a friend's -10 dB and -15dB ones, which were too much. Ended up buying a Goldenjacks -6 DB. Absolutely no perceivable detrimental affect on s.q,., but made all the difference in making all my sources show within the VU meter range.
