  • Crown xli vs xls

    I know the xls are newer, class d, and offer electronic crossover, and that the xli are class ab.

    Which series sounds better? By this I mean more like a two channel home amp. And how do they compare to a standard hifi amp, especially considering their affordability compared to most home amps?

    Thanks

    They sound the same to me. Both Crowns sound better than my HT Yamaha and Pioneer receivers at higher volumes (low sensitivity speakers) but I attribute that to the headroom. They all sound the same at normal listening levels in my room (~80dB at 8 feet).

      Good info. So is it safe to say if you had to choose one of the two for 2ch listening (all other options aside) you would go with the class d due to weight, efficiency, and features?

        I lean more toward a/b but have no reason other than old school. The watts per $ is quite high with the XLi so I usually buy more power. TheXLS with the built in filters is hard to beat. I've got an XLS on order so I don't have to choose...

          I am going to order an XLI 2500 soon as a backup amp for home audio.

          I had the XLS 2500 once as a backup for home audio but sold it. It sounded decent but prefer not to add an additional AD/DA conversion if I don't have to since this is happening in the XLS regardless of settings. It had a bit off hiss from the speakers (96dB sensitivity) if I put my ear within a foot or so of the tweeters. The XLS fan was very quiet at first but got just a bit louder as dust got pulled in. I think every amp with a fan needs routine cleaning! For me, weight, efficiency and features aren't really factors. I never moved the XLS around much, found other amps also fine with idle power consumption (I leave amps on 24/7 and when listening to them rarely play them very loud), and left the XLS in stereo bypass.

            XLi has the same hiss. There was a good article over at Elliott Sound Products concerning where the hiss comes from...I can't seem to find that article

              Good timing.

              ​I have xls1502 amps running some HE drivers actively: JBL 2035HPL 15" midwoofer and JBL 2446h 2" CD with big waveguide (97dB and 111dB @ 1w/1m, respectively). The hiss I get from the crowns - and it is, no doubt, the amps' noise - is apparent. I can deal with it for movies because we typically watch movies from the back row since that's where my daughter likes to sit. The back row is 12 feet away the hiss isn't noticeable, at least to any degree I've noticed it. However, when listening to music from the front row at about 8-9 feet away the hiss is an annoyance namely during quieter passages of music. But again, the CD has 111dB sensitivity.

              Lately I've been considering other options to remedy the situation. I wish I could find the 1 watt SNR spec for the Crowns to compare against some other brands but so far all I've seen is their "at full power" spec which still isn't too great for HE speakers. All that said, for nominal sensitivity speakers (85-90 dB @ 1w/1m) the hiss isn't an issue that I've found. And that's the only downside to the Crowns in my system. If you don't have HE speakers or you do but don't foresee yourself using the Crowns in a 'critical listening' situation then they're probably the best bang for the buck out there.

              Just my $.02.

                Have you hooked up the amps to your speakers without any source connection and shorted inputs? That would eliminate the issue if it's source related.

                As a relatable system that my friend Matt had, it seemed that it was ALWAYS front end equipment. Mind you, hiss was always present, but changed with different front end gear in terms of level and type of hiss. His were pro speakers that were 95dB+, and he fought for awhile to reduce the hiss in his system. Reducing the amplifier gain level also can help.

                  If you're asking me then the answer is: yes. The problem is with the amplifier/HE combo itself. I have tried various combos over the years and it never remedies the situation (other than cutting the gain like you said which just lowers the output to an undesirable level). I've routed signal directly from my Oppo 103. From my AVR. From the Oppo --> Rane RPM88. AVR --> Rane RPM88. Not that you necessarily need that info... just stressing the issue being the amp.

                  ​But, again, this may not bother others and I doubt many are using the crown on a driver with 111dB sensitivity. It's just that it bothers me and it's one of those "once you hear it..." things.

                      Steve, I don't think it's that one. I have it on hard copy somewhere...

                        I have XLS 1502, Very very powerful (obviosly). Sounds clean. Not sure how they compare dynamically to other amps. I have not yet done testing with my other 50 watt amps.

                          Agreed it's more of an issue with higher sensitivity designs, no doubt. Matt fought and fought with reducing the hiss.

                            ​I've been looking at either getting a different amp for the CDs but finding one with good specs that I can afford or a mfg who provides the spec at 1w instead of full rated power is very hard. I've also considered going a different route entirely for my 'critical listening' (namely, the Kef LS50 wireless).
