Post Subject: Re: power supply considerations & scalePosted by guy sergeant on: 6/7/2006
I have a preference for making the power supply a certain way and using certain types of components. If I do that and am consistent about it, I can get better results from some of those old tubes than I can from the more recent types.

But hearing one 845 amp in one place with one type of (probably inadequate) power supply, hearing a different one somewhere else and then maybe hearing a 211 or a 300B amp and from those experiences forming opinions about the 'sound' of those tube is flawed. I'm not suggesting that is what you have done but it is what many people seem to do. They form an idea of the sound of the 845 or the 211 or the 300B but there's no consistency in what powers each of those amps.

On the subject of putting 'scale' into your playback I'm not sure I agree that it can only be done by the speakers. I'm probably thinking more in terms of dynamic range but I've heard phono stages and power amplifiers that sound correct in many ways but very small or constrained. The line stage I'm listening to at present sounds 'huge'. Not in terms of the size of instruments or the spatial presentation of anything but in an unlimited, generous, unforced and very natural way that allows the music affect me more deeply. This unburstable characteristic is also audible via some small bookshelf speakers I also have.
