System Help

Beg to differ...

Suggest not considering any gear changes until well after exploring room setup and possibly treatment first.

Start with Cardas Speaker Placement: http://www.cardas.com/room_setup_main.php
You try both ways on long or shorter walls.

Your seating distance should make about an equilateral triangle with the speakers, or experiment with the seat a foot or two further back. Even 6 inch increments can change the way your ears interact with the room. Little strips of tape on the floor at various increments can make it easy to repeat the placement of the speakers & seat. Try a few combos with a couple of hours of listening at each.

Try something absorptive or diffusive at the 1st and 2nd reflection points which are easily found by moving a mirror along the wall until you see each speakers' reflection easily from the sweet spot. These are key locations to avoid glass framed pictures etc. Echo, treble-ringing etc. are what's affected.

Bass traps in the corners on the front wall are quite often a big help. To get an idea, you can drop a couple of rolls of pink fiberglass insulation (you can even keep in the plastic bags) in the front corners. Also try a heavier fabric blanket etc. hung on the wall between the speakers. These temp. steps will give you a "quick & dirty" idea of what proper room treatment will do for you.

Lots of useful threads in the archives here on setup, also in Ethan Winer's forum on Audio Asylum. Cheers,

What once was a marvelous listening experience has turned into a diffuse, muffled, lifeless, boring system!

If these symptoms are particularly extreme, they would seem to be consistent with a polarity reversal in one (and only one) channel.

Just to be sure something simple isn't being overlooked, are you certain that + and - aren't reversed on one of the speakers, or on the corresponding amp terminals? Also, if you are using XLR cables for any of the analog interconnections in the system, that you weren't using in the previous location, a wiring error in one of the cables (interchanging pins 2 and 3 at one end) would have the same effect. Perhaps an erroneous setting in your playback software could also do the same.

Also, what DAC are you using?

I would not rule out either wiring or amp power shortage. Easy to recheck wiring. But you also should remember that your listening space volume has increased by about 65% and room length has doubled! Those are big differences. How has your listening distance changed?

"How has your listening distance changed?" What I was wondering also. How I'd love to have a room that size again!

Would you please take some pics of the room from all major angles (1st from seating position, then from N, S, E, W so we can see what the room looks like, boundaries, etc....Also, what's the status of furnishings, wall & window coverings, etc.....if something is eating sound, be it room geometry or other factors, seeing what it all looks like and how it is laid out will help.
