Guys, has anybody heard an XPR-2 Klipsch RF7 II combo?
I am well aware that the XPR-2 provides more power than the speaks need. I'm looking for an upgrade on my current 2 channel system and I listen to my music very loud at times. I was thinking about a Revel F208 XPR-2 Combo but I'm worried the Revel's won't go loud enough and I'm tired of blowing speakers. My concern with the XPR-2/Klipsch combo is the hiss factor. I've heard highly efficient speakers don't play well with high power amps because of the ever present hiss. The xpr-2 in particular has been called out for hissing at times, seems like not everybody has it but more than a few do.
Looking for opinions on this subject. Forgot to mention using a XMC-1 as the pre-amp.

I have never heard the XPR-2 with Klipsch RF-7iis, but I use an XPA-5 and the sound is great. I would say get an XPA-2 or two XPA-1L or XPA-100 and save some money.

I had psa mt110's (95db efficiency) with an xpr-5. And here was no difference between it and the xpa-5. So the extra power isn't worth it with your speakers. Ymmv

Here's the skinny on what I know about Klipsch and Emotiva amps.
I've owned.a set of KF-28s not the top of the line but enough to get my bearings as to how a Klipsch tower will sound. Also used Reference BookShelf speakers with pretty much the same results. I've used a XPA-5, XPA-1Ls and a set of XPR-1s. Each set up in amplification has garnered a better response and sound from these speakers. Each amp had created a different and better sounding speaker in every way.
More dynamics! Better defined highs and lows with mids sounding,,,,,,like mids.
I looked at the 7s and really wanted a set but my room is too small to let them really breath all of their goodness into that space.

I have an XPA-2 and have heard no hissing at all.
It is for sale BTW, not listed yet.

Yep I would rather go with XPA-1 or XPA-1L and be very happy. Yeah the Mono 'fier club here will back me up. Because yes they are that good! Also you could save the money for say more music to buy and listen too.

Forgot to mention using a XMC-1 as the pre-amp. The Revel F208's are 88db efficient - inefficient compared to your Klipsch. Revel specs them to an amp of 50 to 350w. Since a speaker is measured for efficiency by measuring it with 1w at 1 meter. The F208 produces 88db at that distance with 1 watt. 2w produces 91db of sound - 4w gets you 94db. In other words each doubling of power produces on average 3db more SPL. 8w = 97db 16w = 100db (getting real loud now) 32w = 103db etc etc I think the Revels would be able to drive you to deafness in no time at all - and it would only take a 250wpc amp like the XPA-2 or a pair of XPA-1L's. Anything more is 'headroom' - something you'll seldom if ever use. Try not to get suckered into the 'headroom' BS. Power not used is money wasted IMO. Power not used won't give you more dynamics - won't 'lift the veil' - won't give you that 'airy' sound you've been lusting for. But it sure will drain your bank account quickly.

I did side by side comparison between the xpa-2 and the xpr-2 for my 86db 4ohms speakers. I found the xpr-2 smoother and less congested then the xpa-2, more refined and not that edgy. And this comes from somebody that doesnt like waste money so at the end i just followed my ears.

Guys, has anybody heard an XPR-2 Klipsch RF7 II combo? I have a pair of RF7-IIs and used them for a time with an XPA-2 in my theater system. Never heard any hiss, and they would certainly play as loud as you could stand. They're now in a different room on a different amp. I assume you've heard the RF7-IIs and like them? If not, I'd suggest you compare them with some other speakers. For the money you can do better.

Heard a few complaints with the 31 dB gain structure of the old Gen 1, but not with the Gen 2 @ 29 dB.

First of all the RF7 sensitivity is 101db. The XPR2 should easily power it to room shattering levels. While the Revel F208 is a much more common 88.5 db and may could use the eatra watts in a large room.

Klipsch loves to trumpet the efficiency of their speakers however many real-world users have measured the efficiency of the RF-7s and most come up with a real world number of around 94-96db efficient. Still very efficient. I've read some of the posts over at AVS from speaker designers/builders about efficient speakers and the measurements they've taken on speakers like the RF-7's. Either Klipsch overstates the efficiency ratings or those guys (who know more than I ever will about speakers) have meters and gadgets that are not calibrated properly. If I were the OP I'd be looking for different speakers. While the RF-7's are a nice sounding speaker there are better ones out there. Apologies to Klipsch owners everywhere in advance and JMHO but they are just too bright for my tastes in speakers.

Let me fill you guys in on some more info. One of the reasons I'm looking at the XPR line vs the other lines is I'd like to have a nice amp that can drive a variety of speakers that I won't need to upgrade for a while. Currently, I have Aperion Grand Verus Towers powered by Emo XPA 100's. which are spec'd at 250W into 8. It's not enough power.
To poster brutirati, I understand your math, but trust me, you're not appreciating the volume nor the headroom I need. I'm not saying I listen at these level often, probably like 4 or 5 times a year, but when the wife and I start drinking or we throw a party, the system gets loud, around 107 db on my radio shack meter for whatever that's worth. Several salesman and audio friends of mine were also underestimating the volume I'm talking about until they came over for a "dinner party", lol. Now they get it. Hence their recommendation to look at the Klipsch speaker line. I have not heard them yet, but they are on my list. I'm aware it's usually either a love them or hate them sound.
Another reason I was looking at the XPR line was I heard it's smoother than the other emo amps, which the Klipsch can typically benefit from. I was hoping to hear from some people with this combo, but it looks like there aren't too many out there, and then it itself speaks volumes.

Forgot to mention using a XMC-1 as the pre-amp. I'll simply say I have a practically non-existent sound floor with my Klipsch Legends(see signature below) while my XPR-2 and speakers are idle. The same can be said for the rest of my mix of Klipsch Legends front stage and Klipsch Reference side & back surrounds with my XPR-5. In other words, no hiss. Just like you, my processor is an XMC-1.

Hey Merlin, just so you know....some of the Klipsch speakers sensitivity is overrated. I recently read a Klipsch review in one of the mags that spec'd the speakers about 4db under their rating. Outside of the Heritage line I have found a lot of the new Klipsch lines underwhelming and tinny. Do yourself a favor and hear them in person first. I am a huge fan of Klipsch but since they went to the copper spun woofers their sound is less than inviting a lot of times. I had some 82's in house for a couple of weeks and they could not hold a candle to my older Klipsch speakers. At the same time, I say go with as much power and headroom as you can afford. No such thing as overkill if you can afford it!
Oh yeah...........and have fun!

I'm definitely going to hear them before I buy. I am also of the fan of the buy as much power you can afford camp since I've upgraded in many small increments over the past 3 years and its getting annoying. I'd like to be done with the upgrade game for a while.
Good to hear there are at least some people with the XPR klipsch combo. Still have a lot of auditioning to do.
