Ok,
Just got the XR 45 and replace the XR 25 that I've had in my system for several weeks now (I've owned it since Sept. though and used it in my bedroom).
I mostly expected them to sound the same and the pretty much do, but the slightly edgy top end on the 25 that I've said more than once here NEEDS to be deal with... uh.... is not there on the 45!
Or at least that what it seems like on day one w/ only a handful of hours of break in on the 45.
I'll keep listening and test if it's just my ears at diff. times of the day, but I mostly listening to the stuff that I knew was giving me some probs on the 25. Pretty much no probs on the 45.
I'm still getting it modded, but I could live with the 45 stock.
I'm not totally sure, but it seems like the bass is bit fuller too. Hard to say if I'm just 'hearing things'?
Anyway... I have to say the 45 is totally worth the extra $50 no doubt about that. Sounds like the 25 with it's slight flaws tweaked out -which I guess it is.
If Wayne's mods step this sucker up in any assorted way it'll all be icing IMO.
$300 should not be this good.
