Question for Mr.Pass (Aleph P vs L)

Metric · 31st March 2006, 07:23 PM

I have recently purchased an Aleph 3, and am considering the Aleph P or the Aleph L.

Which pre do you think compliment the Aleph 3 best? I havent been able to find any retail-price for the Aleph L, but I would think that it was cheaper than the P.

I have gotten good offers on both preamps, but I can't decide which to get. The remote isn't an issue, neither is numbers of inputs, since I only plan on connecting a cd-player to it.

I plan on driving my Klipsch RB 75 with my amps.

Any other DIY's out there compared the two, I'd be grateful for your points of view too

Thanks for always greay help,
Per Øyvind

Go for Aleph P. It is more rifined and smooth sounding. My personal opinion is that P is better than L. It is more extended at frequency extremes and more smooth and open sounding. I just think it is superior, but Aleph L is still a very good sounding preamplifier.

I have no experience with neither P nor L.
Nevertheless, I would like to vote for P (v1.0), too.
P (v1.0) has less number of active devices.

I do not know about the original aleph L, but my L clone was not very good the sound was kinda mood, with mediocre HF responce o.k bass and good mid.
On the other hand a friend's aleph P was super all the way, (I borrowed this to compare with my aleph L). I n my opinion aleph P is a truly dream pre, excellent in all respects and as a bonus, fully balanced too.

Considering the single-ended F2 and L and the balanced
F1 and P:

The single-ended circuits have a fairly pure 2nd harmonic and
the balanced circuits have a 3rd harmonic character.

These two sets of circuits are simple and reasonably good
test beds to consider these qualities of sound as they have
no feedback, only a single gain stage, and otherwise mostly
use identical parts.

With all the mythology about preference for even over odd
harmonics, you would imagine the single-ended circuits to
sound better, but -

The sound of the balanced (P) circuit seems to be more
popular than the sound of the single-ended (L) version.

This is also true of the balanced F1 over the single-ended F2.
