Pass INT-30A with Acoustic Zen Adagio


I'm currently using a Pass INT-30A with a pair of Acoustic Zen Adagio speakers.  Based on all review I've read, the reviews of both the speakers and the amp led me to believe that this would be a very smooth, musical combination.  However, I'm finding it to be rather analytical.  Good recordings sound fantastic, but any recordings that are just a hair short of spectacular come across as sounding very bad.  This is not what I was looking to get into, having only a portion of my music that I can listen to due to this problem.  

I have been racking my brain for days now trying to decide if I should switch out the amp or the speakers.  The amp does so many things so well, but so do the speakers.  I was considering a pair of LSA2 towers, since I used to own the LSA1 bookshelves and found them to be the smoothest, most musical speakers I've ever owned.  On the other hand, I could swap out the amp and go back to tubes and get that smoothness back that way.

Has anyone had experience with this amp, the speakers, or even both in combination?

Depends on which model you select I suppose, they are all voiced differently. But except for the late model Sonata which was a 'bit hot' they are fairly balanced with a warm(er) upper-bass midrange.  On older model Preludes (or other models) you might want to be careful of ones that have metal tweeters, and you will note that the Prelude Pluses have nothing in common with the earlier Preludes at all. They have also gotten excellent reviews.

A confession first. I was thinking about the Pass 30.5 integrated, not the earlier model. That said, I will also admit that what has kept me back from buying one is that I really do prefer tubes, not just the the good things that they can bring that is hard to get with SS but also the ability to tailor the sound to match speakers and other components in the system by just changing tubes.. 

I share your priorities, especially after having spent many years chasing the affordable audiophile dream as set forth by the magazines/ reviewers etc without finding anything that really fit. I then stumbled onto the Silverline Bolero's when you could get them at a more reasonable price. And they do it all for me. The have all Dynaudio drivers including Esotar tweeters (which really are a BIG deal). If you have a large room the LaFolia speakers might do well for you and are occasionally available at reasonable prices. They share many of the same drivers with the Boleros but do have back firing woofers that can be a drawback if not considered. Some of the Sonnetina's are also excellent as well. Fortunately there are quite a few reviews and threads on these speakers to help.

At the time I auditioned the Boleros at Silverline's shop I also listened to the small Minuets (stacked) driven by an inexpensive SS amp and unimpressive CD player. I dammed near bought them instead of the Bolero's, they were that good. 

FWIW the Silverlines are all designed by Alan Yun, one of the premier speaker designers in the business who, interestingly, is not a slave to some 'industry standard'. He has a really good ear, I think.

Hope that helps a bit. Oh, FWIW, if I were starting over today, I would get the Prelude Pluses and a good integrated tube amp and wait for the rare occasion that a pair of Boleros came up on the used market! :-)
It would be helpful to know the rest of your system, cables in particular. Particularly if you are coming from tubes and are using silver cables, to make a gross generalization, the combo of SS and silver can certainly come across as bright or analytical. Perhaps some experimenting with ancillaries might be done before you start swapping out equipment and speakers.
 I had a Pass x250.5 and a 150.5 amp a few years ago,Focal Utopias,Dynaudio C4 and then Raidho C3s at that time as well..The best combo was with the C4s with the Pass stuff .I wound up with a Plinius amp running the C4s which I really liked if I remember correctly then a MC402 which actually sounded better to me as it had less speed and accuracy I guess,if that makes sense.A far as this integrated you have I heard it with Dynaudios(not sure of the model) which always seemed a speaker paired with Pass and Wilsons.I actually just bought a newer Plinius this time as  an integrated,havent received it yet but hoping it will do what I want it to.I know this is vague but I wasn't taking notes and have no speaker suggestions for you.
Forgive another brain fart on the Pass 30A which I find IS based on the 30.5 amp. But you knew that. :-)
