Upgrade for Paradigm Prestige 75F?

thanks gongli3, My friend has some harbeths that I like a lot.  Much more lush in timbre than my paradigms (can't remember the model but on the less expensive end of the line).  The Prestiges do better with soundstage and detail though.  I'll look into Spendor.  I was also interested in Revel.  Anyway, thanks for the suggestion

thanks sbrents73, I thought maybe it was the peachtree that was the culprit of the harsh high mids but I tried it with some different speakers (at friends houses) and it didn't have that problem.  I think its the speakers that are responsible for the sonic signature.  I think I'd rather focus on the speaker part of the equation rather than getting a new amp (as cool as the Anthem might be)

Thanks Adam. I wasn’t trying to infer that anything was wrong with your Peachtree, but you pointed out that there were a lot of aspects about the speakers you liked so I was trying to point out that you haven’t maximized them to their fullest potential. Anthem and Paradigm are built off of each other and speakers are an instrument. Just like if I handed the same guitar to Jeff Beck and Eric Clapton and had them play the same tune, the guitar would sound drastically different. That is also what ARC Genesis will allow you to do. If you want your speakers to sound as if they were running on tubes, ARC will let you roll off your mids and high frequencies.
Changing the speakers means you’re looking for a different tone - like if you had a Fender and now want a Taylor. Just trying to present some options...Thanks again!

That Paradigm has an aluminum tweeter that many find to be bright sounding. If you want a floor stander there are some nice Spendors listed here . The A5r is a 2 1/2 way like your Paradigm. I doubt you would go wrong with them!

Unfortunately, there’s a huge misnomer that driver material is the Biggest problem with speakers.  While the material can interject it’s own inherent characteristics into the sound, it’s the crossover that dictates what those elements will do or don’t do and when people hear something they don’t like, the driver material is generally the easiest and first thing to get blamed.    
The cabinet/environment that those drivers are put in will affect things as well, but a lot of it circles around the crossover and just because someone uses a really expensive fantastic material for a driver when designing a speaker doesn’t always mean they knew what they were doing with it.  Best example of that is Bowers using Kevlar.  When the patent ran out, you could find Kevlar on $399 Sounbars at Walmart, but the Kevlar didn’t make those Soundbars sound like speakers worth a thousand dollars.  They used a cool material that had no bearing on that product’s performance.  Bowers had been using Kevlar for twenty years before anyone else.  Then there’s budget.  What’s the target price point for the design?  That influences a lot as well.  So, in the end, driver material doesn’t play the biggest role in the sound of a speaker and that’s what I wanted to get across here.
Thanks.
