Pass Aleph 5 vs. Pass XA 30.5 / 60.5

I also owned the Aleph 5 for more than 15 years driving a pair of Proac Response 2s. Two years ago I traded up for a XA30.5 that I now used on a pair of Druids. I wouldn't say the 30.5 is necessarily better than the Aleph 5. Just different. The XA30.5, even though its rated at less power, seems more powerful. It swings to the yang side of the spectrum with a more detailed and neutral presentation. There is excellent extension and good control at the extremes. OTOH, I found the Aleph had a more mellow and relaxed presentation that was easier to get involved in. I especially missed its sweet top end.

If you really like the sound of the Aleph then I'd also consider the First Watt amps since they seem to represent a further refinement of the yin side of music reproduction.

I still have my Aleph Os in my secondary system. I moved it to my primary system for a few weeks to try out these bookshelf speakers. As good as the Aleph was in those days, the X- and the XA- series are just in a different league all together.

The mellowness and the relax presentation that Hew indicated was the characteristics that my wife fell in love with and she "mandated" that I would not be allowed to sell that amp. But with the bookshelf speakers I was checking out in my new dedicated room, it sounded a bit veiled and sluggish when compared to the X350.5.

Aikidoka,

What preamp do you have?
The XA amps are truly balanced. The Aleph amps were not.

I think, 90% of all Aleph's are used with the wrong speakers. The Aleph Design
was never designed to drive the majority of speakers, it is sonically comparable
to a Single ended Design (--> balanced Design or not is irrelevant compared to
X, XA Design) and Speakers should be seen from that view.
Matched with a high sensitive speaker (past X-over!) the Alephs are even today
very hard to beat from sonic quality (speed, airy headroom, pace...). MUCH
better than the X or XA series.
It is a different chapter when Aleph is connected to a speaker which is a load for
them (lower sensitivity), here the newer Pass amps show their advantages. In all
those discussions the speaker loading is crucial.
When I used a 99dB Speaker with stable 8Ω and I made my comparisons
with X, XA I never was able to listen to these more than 20min, dead, cold,
clinical, not natural... (like the products from other manufacturers, too), far
away from a lively sonic presentation. Aleph connected to a Speaker from
Burmester, Magico, Thiel ...are disappointing compared to amps which were
designed for these loads. All their merits are gone then...With those Speakers
the newer Pass Designs are better.
When you want to keep the audiophile life as simple as possible, think about
Amplifier AND Speaker as one - matching - unit. The Alephs are even today a
sonic milestone compared to the rest of the world, but only with the matching
Speaker Design.

And if you add a decent SW to the Alephs, OH MY!
