Pass Labs Aleph Question

I also had the Aleph 2s with Dunlavy 4s. I went from the Aleph 3 to the Aleph 2s on the Dunlavys. I thought the major improvment was in the bass going to the 2s. There was always something I liked better about the sound of the Aleph 3, there just wasn't enough power for the Dunlavys though, and even the Aleph 2s with the Dunalvys wouldn't rock the house. I consider the Aleph 2s to be a weak 100 watts. They are great sounding amps though, just not powerful sounding amps.

Im with you TD. I have found out that if the 4a's arent set up properly or the room isn't working with them, you can have a krell fpb 600 hooked up to them and the bass isn't going to be right. Good thing for me, I have an ideal setup, a fairly small room 13X18 with the speakers on the long wall. I actually was between amps and had to borrow a 5 channel B&K av 5000 amp rated at 110 wpc and the bass was fine. So I can't really see the aleph 2's letting me down unless they're just bad at reproducing bass. Ejlif, How big was the room your Dunlavys were in?

The room was 18x25. I went from the Aleph 2s to the BAT VK150SEs and the bass as well as everything improved quite a lot. I really do love the Aleph sound, I just don't think the Dunlavys are the best match. I had better luck with the Silverline speakers with the Aleph amps

I have 2 Aleph 5's and they are one of the finest sounding amps I've ever heard. Drawback, only sound good when warmed up (at least an hour), will double your electric bill if you leave then on and aren't suitable for difficullt speaker loads. Match then up with some fairly efficent speakers. I have B&W Nautalus 802's and they work fine.

I have the Aleph 4's which are a stereo version of the Aleph 2's. I corroborate those who say that the Aleph
amps are some of the finest ever made. They are extremely neutral, deliver tremendous detail in the highs while always sounding natural and unforced. Even the most minory colorations which I find in my system are always proved to exist elsewhere, not in the Aleph 4's. I use them with the inefficient, 6 ohm Vandersteen 3A Signature in a romm which is 22'x12'x8' and which is open to adjoining spaces. There is no bass problem. Bass is extremely deep and will do any pipe organ recording justice. This amp can rattle floors and windows if you are into that. What it doesn't do is give you the ultimate bass slam. The bass is not super-tight and punchy, but who cares! It is a wonderful amp in every respect. I have heard the Pass X series (X350 and X250). In my opinion, they don't compare for naturalness and for absence of all electronic artifact. Sorry Pass Labs, but that is my opinion. The fact that they developed the super-expensive XA series, followed by the X+ series in order to bring the sound of the Aleph to the X series would suggest that someone was not completely satisfied. I say just save your money and buy an Aleph. From some of the posts here, you might want to stick with the more powerful Alephs. I have heard the Aleph 3, the Aleph 4 and the 1.2 (200W monoblock). The 3 did sound a little underpowered in certain situations, but it is also a wonderful amp.
