Pass Aleph 5 vs. Pass XA 30.5 / 60.5


Hi! Currently, means for the past 15 yrs, I own a Pass Aleph 5 to my great sonic pleasure. Would it be a wise idea to trade it in for a pass xa 30.5 or a pair of xa 60.5? I´d be glad to get a comment!

Yes. I have owned the Aleph 3, 5, 2, XA 160, XA100.5 and now the XA160.5. The Aleph 2 was substantially better than the Aleph 5 and the XA.5 series is a whole different level. I have not owned the 30.5 or 60.5, but I heard the 30.5 with my speakers before I bought them. They did not have enough power to drive them properly.

I owned the 100.5 at the time and it is superb. I imagine that the 60.5 is close and would be fine if your speakers are efficient and the room is not too large. The mono blocks in both lines are better than the stereo versions. The biggest improvement is in the control of lower frequencies, but there is also a real sense of ease. They are much quieter than the Alephs with less distortion. Timbre is excellent. I go into more detail in my review of the XA100.5 which you can access by clicking next to my signature.
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.
