X-Series vs. Aleph

wuffwaff · 7th January 2002, 11:18 AM

Hi,

did anybody ever compare an x-series with an Aleph?
A few years ago I had an Aleph 0s at home for 2 weeks or so. It really impressed me (more than some big american competitors) with it´s sound. Recently I´ve tried an X150 (also for 2 weeks). Although this also sounded fine, it didn´t impress me as much as the Aleph did.
Of course this is just a comparison between 1 model of each series with a lot of time in between but maybe somebody else has made similar observations with different models?

All other things equal, the X amps have more dynamic
range and more control in the bottom end, while the
Alephs are warmer in the mid and a little sweeter on
the top. If I only needed a few watts, I would tend to
pick an Aleph, but if I needed more power, an X.

At CES tomorrow we will show the XA200, which is
an Aleph Single-ended Class A output stage mated to
an X front end in what I refer to as "balanced singled-
ended" (an oxymoron if there ever was one).

My experience with the prototypes and initial product
is that it comes very close to delivering the best of
both worlds, and is the best yet from us.

Recently Grey speculatively worked up a schematic of such
a creature, but he hasn't tested it yet. At my request he
graciously held off publishing it until our product
announcement.

I anticipate that he will release it soon, particularly if
you all begin clamoring for it.

I was wondering when someone would bring the two together. I'm sure it will be a stunning amp.

I've been thinking about such a beast for a while also .... clamor, clamor, clamor.

So, I worked for Nortel Networks for years, and they always sent a design team to CES along with the marketing doofuses (doofi?). Never got to go (never really wanted to).
Now I'm disappointed I can't see and hear this new amp and perhaps even meet Nelson.
Now I work for Panasonic. CES? I don't think so...

Nelson,

your description of the differences about fits what I experienced. I even thought the Aleph showing more inner details throughout the frequency range.
