Didn't you know? Ashley fancied (still fancies) himself as a scientist, and so got a hard-on from slipping his white lab coat on (with matching knickers) and calling it the 'Laboratory Series'! :lol:Quote:

Also, he thought that the name 'Laboratory Series' would evoke how the equipment had been designed with the emphasis on measurements, and thus this would give it kudos in the eyes of the impressionable (some would say, easily impressed) objectivist fraternity.
Rather laughable, huh? :D
Marco.
I think that's wrong Marco ;) To me it sounded sterile, it had no life like decent kit does which makes the music sing. We all know laboratories are kept sterile now don't we :eyebrows:Quote:

The AVi is astonishingly good in the bass, Mark.Quote:

"Sterile" .... mmmm, in the wrong system, maybe. It is a bit forward in my system, but very transparent and detailed (partly because of the slight treble emphasis, I am sure).
I was getting bugged by that Jerry, but having thought of what I just mentioned in my last post I reckon I have a good idea why that is & why the thing sounded a bit bland to my ears.
Loadsa feedback :(
Feedback loosening up the AVi pre's bass you mean, Mark? You used LPs exclusively in your pre-amp comparisons?
(I've slightly updated my last post, btw!)
Ha - and that's also what happens when you trust the readouts on oscilloscopes and spectrum analysers more than you do your own ears! ;)Quote:

Marco.
Not really no. The Krell being what it is will be a discrete circuit in full class A from input to output & run at high current so it could drive just about any power amplifier over long distance cables. If I remember right the output impedance is almost low enough for it to drive an 8 ohm speaker to a Watt or so :eyebrows: Along with this the circuit uses low amounts of feedback, it doesn't need great gobs of it to lower the distortion as it's inherantly low anyway due to the very heavy class A operation.
The AVI on the other hand sounds like it's using a great deal more feedback, this would explain it's possibly greater bass control (system depedant of course) & it's kind of bland presentation that I heard back in the day.
The thing with feedback is it increases (up to a certain point) the lower frequency it is producing, so it could well have loads of control at the bass end because it has a shed load of feedback, but at the middle & upper frequencies all this feedback isn't the best way of getting a musical presentation IMHO.
If it was we'd all be listening to Technics amplifiers :eyebrows:
E2A:- It was exclusively CD listening on speakers & power amps I was very accustomed to.

The problem is that the pseudo-scientist brigade amongst audio designers, in the quest for 'perfect' measurements and the tightest bass, surround their kit in so much feedback, that it strangles the life out of it, and thus prevent it from allowing music to 'breathe' naturally.
I always find it rather educational when experimenting with reducing and increasing the feedback on my copper amp, by applying the use of various resistors, and the subsequent effect it has on how convincingly it reproduces recorded music! ;)

Now you know that & I know that & as I'm all to aware at least one engineer on here knows it to :)Quote:

Nice to know we agree on at least three things now :D
