ProAC 2.5 users please share experience on amp

Derick, it sounds like you're experiencing the bad sounding violins when the music becomes louder and more complex. Solo instruments or chamber music settings are more forgiving, but when you get 10 or more violins going full bore, things can get strident.

This is something I exprienced a few years ago when I first started the hobby. I don't have a real explanation for how I was able to overcome much of this. Better equipment? Adding tubes to the system? But I know I've seen this mentioned in the forums before, so maybe a more experienced person can comment on this.

I currently own both the ProAc 2.5s and the 1SC. The ProAc 1SCs tweeters are anything but hard and glary. I like a warm sounding speaker and after much auditioning settled on these. I also had a pair of Totem 1s which were very good and much brighter than the1SC (at lease in my room), in a head to head match up the 1SC sounded better so the Totems after holding the spot in my system were sold. Matching a tube preamp with a SS power amp seems to work best in my system and with many others using the 2.5s or 1SCs. I use an Pass Aleph 3 with a VTL 2.5 preamp with the 2.5s with excellent results in a modest size room. In any event both a great speakers, I find the 2.5 similar to the 1SCs but with much better bass and a fuller sound. Just a note good stand are essential with the 1SCs.

Pass Lab alph 3 has only 30W/channel, you think it will drive 2.5 well? What type of music you mostly listen to?

As Gunbei said, the problem I experienced now is the difficluty to let proAC/cary present the complex music (like symphonie). I don't need kick bass, but just need a well balanced, positioned,layered sound which is some kind
of missing in my current combination.

Any suggestion?

Derick,

The Aleph 3 is great sounding amp. I borrowed one from Viggen a couple summers ago and really loved the way it did guitars. Better than any amp I've had in my system. The Aleph 3's soundstage was deeper than the other amps I tried, but I felt the width was constrained to the speakers. The BAT VK200 on the other hand threw a soundstage that easily extended outside the speakers.

It was really difficult for me to choose between the BAT and the Aleph, but what tipped the contest in favor of the VK200 was Aleph 3's low input impedance of 23Kohms. My Blue Circle BC21 had a hard time driving it, and when I wanted to crank it there wasn't enough juice.

Careful preamp matching is a must with this amp. It seems Gjrad's VTL works well with it. I've also read that many people like the solid state Aleph L or Aleph P with it. I know I've read other threads about tube preamps that matched well with it, but I can't remember them.

I just read speaker review at Speaker Asylum, (link: http://www.audioasylum.com/cgi/m.pl?forum=speakers&n=67219&review=1)
The reviewer get almost same experience on the symphonie. "...but when things get cooking the violins get a little massed and lose some of the sweetness that makes them so beautiful in live performances. Also very difficult/impossible to get them to layer the orchestra properly..."~~

of course, I also got the same outstanding result with solo cell, which one of best i ever heard~~~.

Well, is this becasue of the "weakness" of equipment(JRDG Concentra Int Amp(SS) ) he used or it is ProAC 2.5's own weakness..?

I am wondering......... ANY comment~~??
