    Well, you will indubitably be able to increase the gain but you might end up losing that utter transparency that sucked you in in the first place. I'd be happy to be wrong but a limiter is an awful lot of electronics to go through for a bit of gain if you don't want the sound altered. IMHO, of course. I hope it works but, if it doesn't, you might want to try using a passive level controller like this:

    Thanks for the heads up. If something goes awry with the limiter from dbx I'll totally check out the ATTY. I'm also going to be using a pro, two-channel tube preamp too. I'll be playing with combos for a while I'm sure.

    Can you tell me where your gain is set? Also, if I read this correctly, with the Pendragons you are using 2, XLS 2000's per side in bridged mode, correct? I am curious to know what differences you hear if you compare it to running a single XLS 2000 in stereo mode. I know you said you preferred the bridged scenerio but you didn't elaborate. Thx.

    I have the gain set to 12 o'clock and compensate about +3dB in my Integra AV preamp to get to 75dB on my SPL meter at my listening position. Since my rear channel speakers are not as efficient as the Pendragons I have to compensate inside my Integra +8.5dB to get to 75dB. Side note, you don't need to mess around with limiters or the like if your preamp has the dynamic range to overcome the differences between pro and consumer gear.

    I run the mains in bridged mono mode and there are subtle differences, but I could just as easily be happy with the 2000 in stereo mode if I didn't have the extra amp or cash to acquire a second. In mono the Pendragon's bass is just a bit richer, tauter and deeper. The midrange has slightly better definition and dimension and the tweeters, well, they're just a bit more refined. Again, I'm talking single digit percentages here and not in huge leaps of 10 and 20 percent. The nice thing about the 2000 is that in order to get that last percent increase of performance you needn't spend tens of thousands more. If you're happy with a single 2000 I would say stick with it and enjoy. If you feel the urge to upgrade only do it at a later date once you feel you've wrung as much enjoyment out of the 2000 you have already.

    Thanks. I am actually running a single XLS 2500 not the 2000. One thing I REALLY like is the rich, deep, but also very articulate bass at the lower volumes. This amp really has a tremendous grip on the drivers. I am not missing my tubes right now. Getting better and better as the hours build up on this amp.

    Just thought I would post a few photos of the crown's for any one that might think pro gear has to be ugly and utilitarian. I now have a 2000 for the tweeter and mid, and a 2500 controling the bottom end. I have owned a LOT of amps in my days, many very high end ones as well. I find it hard to admit, but I gotta say....these are the BEST sounding amps I have ever come across...AT ANY PRICE!
    The top end is clean and clear, without being fatiguing, the power they put out command and control the bottom end like nothing I have ever come accross. There is a crisp "snap" to the drum beats that I have never noticed before, and everything is just so, well...as my friend puts it, "clean and tight" The remarks about the sound being un-colored are very true though, if it's a crappy recording, you will know after about 1 second.

    Before the Crown's I could never really tell a diffrence between digital recordings of LP's that I saved to my computer and played through the DAC or the real LP...now I can. Yes, it's that detailed...almost too much so. Having said that, the warmth of a LP sounds much better with the crowns, and I'm going to bet with a tube pre-amp, this set up would rival some real high end stuff! Hats off to crown, this is great stuff!
    Now if I can just get the idea that some 90 year old woman at my local K-mart is probably using the same amp to announce the lasted "blue light special" out of my head....

    Neal98,

    Welcome to the forum first and foremost and thanks for sharing your pics. Your system looks great and I bet sounds amazing. Don't think for a second it's not high-end or high-end sounding for I assure you it is. Just rest easy knowing you achieved high-end nirvana for a fraction of the cost. Enjoy!!!

    I could not agree more. I've had mine in my system for about 10 days now and I am convinced this is the best amp I have owned to date. The amount of grip and control it has is second to none... I get the feeling I am sitting in front of the performer. It so easy to follow the bass lines now... tone and bass articulation is awesome! but again, I am mostly in to live recordings (live rock and contemporary especially), so it is questionable whether it would appeal the same way to an audiophile that listens to music for utter detail opposed to the emotional aspect of it (or the music itself). The amp itself seems to be very transparent/uncolored, but at the same time, never sounds cold or harsh to my ear and I am very sensitive to that. Again... I am using a Cary CDP-1 cd player as source and pre-amp as it has a volume control built-in. I am also using rca as I have yet to try xlr at this point.

    I realized I haven't yet posted pics of my new XLS 2000s. Here they are in my Sanus rack. Oh so pretty.
