Amp for Paradgim Studio 100

The "faults" of the 100's are a pretty hot treble. Let's not kid ourselves and think the 100's are perfect. They are a great speaker at their price point.
The EC tamed the hot treble and did a great job of letting the music extend out from the cabinets. Again, your mileage may vary. Go to some local dealers and listen. Ask for an in home demo. Good luck.

I have the 80 V-1's.
same tweeter as the 100's
yep,they can sound hot alright.
even with a tube pre and a smoooooooth aleph-3 they were still a bit bright.
I found the only way to tame them was agressive room treatment.

A used Levinson amp with Audioquest cables might do the trick. Both are neutral throught the bass and mids with a slight roll-off of the highs. Or, you could try tubes.

Thanks for the clarification, Celery. I certainly do not see the 100s as the be all and end all of reproducers, though I'm very happy with them in my HT setup. I find that many folks who accuse them of having a hot top end really are hearing a rather laid back midrange that doesn't come forward and join the band until the speakers are played at medium to high levels. Just my opinion, of course. I also think that some folks, remembering the early efforts of tweeter manufacturers, learn that the 100 uses a metal dome tweeter and just assume it's going to be hot.

With the version 2's, I haven't noticed any real brightness -- my understanding is that the v2's are a big improvement over the originals in overall smoothness of response. My room is pretty "padded" -- lots of carpet and acoustic tile in the ceiling -- so I could be missing brightness if it's there. I think the Bryston 4B-ST would be a good match (though, if you can swing it, I'd still opt for the Sierra if you are using this as a primary audio system).
