Amp for Apogee Stage's

morbius,

Krell is a fine amp for solid state. I believe Boulder would better. Both
represent an old technology. The new fast switching technology is sweeping
acceptable standards set by transistor powered amps aside.

Accuracy doesn't just apply to frequency response. Timbre truth depends on
speed as well. You can't hear a string instrument's full character if subtle
sounds made by twisting of the bow is missing. That comes with speed, and
an amp's ability to fully support the loudest, and softest signals
simultaneously. The H2O has that speed, and separation.

Say, what do you think about parallel universes?

Muralman1,

When I say "accuracy"; I don't mean just frequency response.

What I mean by "accuracy" is the shape of the voltage waveform
to the speakers is EXACTLY the same as the voltage waveform
that represents the music.

The frequency response is just the Fourier Transform of this
waveform. However, my definition of "accuracy" is more
detailed than that. In my definition of "accuracy" - the
voltage on the speaker's terminals has to look EXACTLY like
the music it represents.

There are tube amps that can reproduce accurately - depends
on the design and power capacity.

As for parallel universes, I'm afraid I don't delve into
cosmology - think the other end of the spectrum - nuclear
physics.

If it's truly parallel, then how do you know it's there?

Hi Jeff,

A lot of scientists understanding of the cosmos is based on mathematical elegance, and conjecture. Some things, like the aftermath of the Big Bang, can be measured. Gravity can be measured, but the source of this weak force has had scientists stumped. Using a theoretical parallel universe model, gravity makes sense. It ties neatly into other space/time theories too.

NOVA has been running a series on it all:

Morbius,

I got the impression somewhere that you work in the area where I live in the East Bay. You might want to listen to my psuedo mini grand system with gutless amps, and I could listen to your system with Krells. Maybe you will sell me and I will change my system and my impressions, I am always open to a broadening of my horizons. Since the speakers are largely the same, it would be an interesting comparison. E-mail me if you are interested. I could run through 1. pseudo high current solid state cascode JFET class AB (Yamaha RX Z9) about 300 to 400 watts @ 3 ohms/passive crossover 2. Bel Canto 200.2 digital amp about 200 watts @ 3 ohms/ passive crossover 3. ASL Explorer 805 SET (50watts)/ passive crossover and 4. Active crossover with 805 SET on MRT and Bel Canto 200.2 on the bass ribbons.
My listening impressions favor 4,3,2 and 1 in that order although the Yamaha would probably qualify as the most accurate.
