That's a remarkable change of tune from you?


Not at all - Keith is sneering down his nose at the quality and
sincerity of such the evaluations I was talking about. Since they don't
agree with his prejudices, they couldn't have been any good.


Still an about face. Everyone who hears *his* system - dustman to doctor -
immediately goes home and throws out their Krell, begging Keith for one of
his SET amps. Or have I read him wrong?

I'm neither a dustman nor a doctor, and when I went to hear Keith's system,
I wouldn't have begged for one of his SET amps, except possibly had I been
in need of a boat anchor. His system *does* sound exciting (as in unbearably
coloured) and that's how he likes it.

Can't explain why Keith gets the reaction from visitors he tells us about
here. Maybe it's something in the air of St Neots.

Serge, I have mentioned before that my 'system' (one of what - 4
systems?) is greatly changed from what you heard and the Jericho
speakers never did 'come right' and have been consigned to the garage.
Right now, for example, I have a record playing through my
recently-acquired valve preamp/Dynaco Mk IIIs into the TLS80s - hardly
the 'triode & horns' that I usually use for vinyl, is it?

My preference for vinyl *is* triode amplification on the Lowthers (the
Holy Trinity) while movies, radio (FM and DAB), TV and CDs (mostly) go
through the SS/TLS80s system according to how I feel. Now that the
Dynies are up to the task (with the new preamp), it will be interesting
to see if they fully supplant the Technics SS pre/power combi that is
also new here and which I like a lot and which has a definite 'heat'
advantage, now that summer's coming. (And which almost certainly has far
better noise, distortion and S/N figures than the 'techno**** clown
bashers' can probably claim for their own kit??)

I suggest you look at my detractors when words like 'bigot' start get
flung around - I, at least, choose from the 'whole spectrum' when I
decide what to play on what.



Can't explain why Keith gets the reaction from visitors he tells us
about here. Maybe it's something in the air of St Neots.



The visitor who has *just left here* (having been here all afternoon)
has, after some 15 years of SS/digital audio, cloned my entire
valves/vinyl system apart from the the valve phono stage which he is
going to have to wait for from World Designs. (A reasonable person might
just stop to consider that he must have heard something significant
enough to prompt his actions - a moron would dismiss this out of hand as
it will not conform to his own narrow, prejudiced beliefs/preferences.)
Trust me that he is no fool and believe me that it has represented not
much more for me than another opportunity to spend my time for the
benefit of another 'enthusiast', collecting only a little out of pocket
expenditure along the way.

.....that said, I did get to buy the valve pre off him very reasonably
and he has just made me a gift of a set of motorcycle brake caliper
bolts (some 20 quid's worth at 'staff prices') to replace those on my
bike which have gone a bit manky:

Please don't consider yourself targetted when I throw my net to catch
the bigots and hypocrites in here - you, Don and one or two other
'intermittent posters' are examples of people whom I might regard as
*grossly misguided* and/or 'missing the point' at times, but I respect
your views/opinions/knowledge/experience and take your comments in the
spirit and manner which they are offered....

I will ask for an invitation to hear the TLS80s as soon as I've finished my
chores round the house here. As I've mentioned before, I used to have a
pair in IMFs myself (the smaller TLS50s ) and I've always regretted getting
rid of them, but they only work back-to-the-wall, so they would be of no use
to me now.

You are already invited, all we need to do is fix a date...

Jammed right against the wall and hemmed, in in my room!! :-)

(I use them as equipment shelves also!!)

That there was a cat to skin is the whole reason for my 'explorations' -
any sane person would have stuck with the little Sony 'lifestyle' system
I mentioned recently and simply wicked it up a bit....
