    Have you tried any other speaker cables recently Mike? They could be a source of brightness. It won't be the interconnects, Straight Wire stuff is well behaved.
    The word is 'valves' in this country, not tubes. Tubes are what Smarties come in!

    Have you tried any mains treatments, Mike? Or experimented with cables? Also, what kind of valves are you using in your amp - modern production or NOS?

    All of the above, IME, could potentially contribute towards the "stringency" you mention.

    Great minds...

    Also, IME, poor mains and cheap modern production valves can be a source of brightness.

    Speaker cable is Van Damme LC-OFC, supposed to be on the warm side I believe. I also use a Power inspired mains regenerator. Not sure on the valves in the Soro, I'll plug the S500 back in tomorrow and see how that sounds.

    It certainly won't be the Van Dammes - not sure about warm sounding, but they're not bright that's for sure. More neutral, I'd say. Mains regenerator sounds fine, what about mains leads - are you using anything decent there (I don't mean expensive), or just standard 'kettle leads'?

    Defo check the valves, as IME a lot of modern production ones, especially Chinese and Russian varieties, can sound a little 'edgy'.

    Perhaps Anthony could comment on this matter?

    So true.... That message needs drumming into every arrogant, stubborn-headed objectivist, who believes that everything that there is to know about audio is already known... Get yer heads out of yer freakin' text books, and LEARN more by living in the real world and applying some LATERAL THINKING!



    Marco.
    If these rather forceful comments are directed specifically at me, I am offended by their tone, and find the post rather rude.

    You can rest assured that they were not. I was making a general point aimed at folk with that type of blinkered, staunchly objectivist mentality, so unless you think that you qualify, then please be blissfully unoffended

    I don't think that I qualify as an objectivist blind to truth, that would be an oxymoron. I do however think that the ear is an overrated instrument, it only transmits an electrical correlate of what it is receiving. The rest is done in the brain and this is very much 'software' (brain) effected, and so dependant on the individual's development.

    My friend calls me deaf, and instructs me to get my ear trumpet, but I can hear the HD on my PVR at ten feet away, and he cannot with better hearing technically.

    I have also designed and built power supplies, and I think I understand the relationship between 'iron', rectification and storage capacitance.

    Well, I'm in no position to dispute any of that, but we'll have to agree to disagree on the importance of 'iron' in valve amps. For me, it's a LOT more significant than you think.

    IME, there's no such a thing as 'too big' a power supply in ANY piece of audio equipment. As long as it's well designed and compliments the partnering circuit, bigger, in that respect with greater capacity (and heavier), will almost certainly mean better!
