There was some hiss when bridged at max gain. I didn't notice any hiss when not bridged, with the RCA inputs. Like with your awesome LS50s the hiss was audible at about 1 ft but not at listening position. With gain at 3pm, no hiss.
Anyone know where to get speaker cables that have Speakon on one end and bananas or spades on the other?
Well, well well. Guess what just showed up? Some Wyred4Sound monoblocks. Let's compare them to the XLS in monoblock mode shall we?Stay tuned...
Say what???? That sure was fast! They should definitely be a little smoother on the high end and maybe a little bit better sound stage. But like you've said before, it's all about synergy with your system.Enjoy!
Change to the Audience Power Chord gave some improvements including to the treble. Things felt a bit more fleshed out, fuller with the Audience. Then it was time to go monoblocks! And whaddya know. Improvements! In the impact of the bass in particular. As those of you who are familiar with SP Tech speakers know, they are known to benefit from gobs of power. And yep. Bass was fuller with greater detail and impact. As for the rest of the frequency range, monos give a greater sense of ease.
So, since this was before your discovery that you were not in bridge mode when you heard this, it sounds like the power supply must be a little under-spec'd, since the difference you heard could only stem from the power supply being relieved of the duty of supplying two channels and being fully available for the one channel you were using. Which implies there might be an advantage to upping the power supply's capability - through more capacitance, perhaps?
And the fun never stops over here. What had arrived when I got home from work? 2 shiny new XLS2000! Couldn't resist those Amazon deals. Got one at the 17% off and the 15% off counted as a different deal. So I could get around the 1 per customer limit. So the tour amp will move on to Chris. I don't have a lot of time tonight, so I'll be comparing the 1500 monos to the Wyred Monos warmed up and into the wall. Unpacking the 2000s and setting them up will be for tomorrow.
