Help. System sounds thin and bright or harsh


Hope this isn't redundant tried to post in Tech Talk

Just moved my system to a new home/sound room and it still sounds harsh and a bit thin despite supposedly "warm" sounding Harbeth 30.1 speakers. This issue is not new and I had put the blame on the old listening room.  Can't figure out what the problem is. I listen loud at 80dcbl or higher and sit nearfield about 8 feet from the speaker plane. (sound is thin and bright from afar as well) I have experimented in both homes with speaker placement, toe-in and the like. Speakers are placed a lil over 3 feet from the rear wall and about two and a half feet from side walls.  I feel something is off. Perhaps a component or two that is known to be tipped up in the highs and a lil bass shy?? Also, I leave all solid state components fully powered up 24/7. (not the tubes)

System:

Modwright/Oppo BDP 105 disc player  (all mods with tubed power supply and pricey NOS tube upgrades throughout)  Looking to replace once the harshness/bright issue is nailed down.

Parasound JC2 Preamp

Pass Labs X250.5 Amp

Harbeth 30.1 stand mount speakers

Puritan Labs PSM 156 power conditioner. (less "edgy" sound with it in system)

System is run all balanced with fairly costly Cardas interconnects.

All input is welcome. Thanks in advance.

Happy listening.

I suspect it’s the room. Throwing money at cables, other speakers, and so forth, seems ill-advised. And don’t some audiophiles just LOVE to spend lots of money in in their pursuit of Nirvana?

Perhaps contacting one of the acoustic panel companies for a consultation would prove to be beneficial. One of the most effective and economical improvements is SQ I’ve made was to assemble 2’ x 4’ x 6" bass traps for the front corners on my rather "bright-sounding" listening room. The 6 Owens-Corning sheets cost about $100, wood for frames about $35, and some inexpensive white burlap about $40. I plan to make a few more thinner (2") panels for first reflection points, and perhaps elsewhere.

Room treatment is on the agenda.  I went through this in the old place with stacking four foot bass traps in corners behind the spks and a massive wool and canvass behemoth behind the couch and an absorber on the wall just behind the seating position. Overdamped to say the least for the 30.1's. Had been trying to tame Harbeth slh5's that were just way too boomy for my apartment. With the 30.1's I took out all the treatments cept for the trap behind the couch and the absorber behind the seat and found I liked the sound much better. Going to try simple cloth or rug options in this new room just as a test once I determine that all the components are performing up to spec.  I've already checked out treatments for the first reflective points on the side walls. Wanna keep it simple and relatively cheap.

Someone mentioned toe in.  I barely have any at all. Adviser at Fidelis that distributes Harbeths said to point them directly at me with hard toe in.  No bueno in this room.  They are not firing straight out but I can see all of the inside walls on both spks.  Not sure if many have purchased the "Get Better Sound" book by Jim Simith.  It's loaded with all sorts of "free" tips...many which I am just up to tackling and sdI still am having problems.. 

Just pushed the harbeths closer to the front wall (from 3' 2" to 2'2")  tried before and after moving seating position forward. First impressions are it sounds a lot worse.  No increase in bass. This seems to run counter to the laws of speaker physics. LOL.  "Something" seems to be sucking some of the bottom end out.  I'm not a bass junky either and I realize the 30.1's bottom out at 50HZ. Excellent recordings are still tolerable but jeese this is crazy.  I am noticing that the volume is a lil higher to get the same sound level. That's a lil odd. So I'm compensating for something with the volume control. Maybe things are a little less lean...but not as loud.???  Isn't this fun!!!

Happy listening

 

I'm not familiar with your speakers, but FWIW since you're moving them around....

IME, floor and bass driver interface (distance between the bass driver and the floor as well as the side walls) goes a long way in determining bass reinforcement. I think someone suggested tilting back your speaker already but lowering your speakers height, which may seem counter intuitive, off the floor in combination with the tilt would make a better bass response. What I would try just to see if lowering the speaker would help just get them up about a foot off the floor (and tilted back so the tweeter axis is pointed at your ears). And go from there. BTW if you want to keep the sense of depth of image keep them as far away from the back wall as possible.

In my room traps and absorbers behind the listening position did not work out so well.
