Grammatical niceties aside, "even more better" might be the most appropriate way to characterize the difference.

The tests were made with the nearest edge of each second-reflection-point trap positioned about a foot ahead of the plane of my ears as I parked in a semi-scrunched sprawl near the bed's midpoint. These photos show them from approximately that perspective.

Left side:



Right side:



(Ignore the glossy-black Paradigm SE-1's on the carpet--they'll be moved out of the room.)

Overall trap placement is diagrammed here:



I was particularly impressed with the increase in: perceived dimensionality and spatial expansiveness of the soundstage; in the sonic palpability of instruments and voice; in tonal "liquidity" (e.g., in the French horn); in dynamic contrasts; and bass decay that enhanced foundational solidity.

Having said that, I'd make two points: First, what improvements I heard built on what I'd already thought good with the scatter-plates in place; and, second, none of the improvements put lipstick on a pig. I purposely played some recordings that I consider sub-par to see if the configuration change would doll them up. Nope. All the increased focus and perceived increased resolution did was simply put me further "into the mix"--and if it was a bad one, its flaws showed even more prominently. But the good stuff--that's something else entirely.

Yeah, well that's all well and good. But the really big question still hung out there. This is a shared space, after all, and while I could play to my heart's content while testing configurations, was this to be just a transient experience, one of those situations where you tread onto the rim of sonic Paradise for a couple of hours only to be tossed out just when the getting's good?

Cue "the conversation":

WIFE: I see we now have two of those things on each side.

[Uh-oh. "...those things." That doesn't sound like anything approaching acceptance, much less approval. But she has a point. The bedroom has morphed into Stonehenge.]

ME: Well, I'm just testing to see how it would sound with them in place. I can always move them ou--

WIFE: No, no. They're fine. And I'm glad you got them in grey. But I worry.

[A moment of stunned silence. I catch my breath.]

ME: Uh, about what?

WIFE: Those things on the back wall. Are you sure they're all right up there? I don't want them falling down on your head while you're listening.

ME: Uh, oh, nothing to worry about. They're hung securely. Two hooks each.

WIFE: That's good.

ME: [Deep, deeper, deepest sigh of relief.]

So we're good. And at the point where I won't inflict any more pics or diagrams on you. What this trapping configuration does is make listening in a space fraught with multiple asymmetries and an unhealthy dose of SBIR issues far more than just "decent" or "good". So much so that I'm almost tempted not to refer to it as the "secondary" system.

Chalk me up as a happy camper.
Very nice right up. Thank you for your diligence.

Having heard me rattle on before about the baneful effects of direct reflections, my wife volunteered to move the cases without any prompting from me. And--also without any prompting--she said it was all right if I moved the 2'x3' framed poster (a Georgia O'Keeffe rendering done for the 1982 Santa Fe Chamber Music Festival) that hung at front wall center to another room if it posed a problem (it did, and it's now hanging in the home office).

An anecdote that will put this all in perspective: When we started going together 36 years ago, she allowed me to drill holes through her living-room carpet and hardwood floor so I could run Fulton Gold speaker cable unseen from my DIY time-aligned KEF/Audax hybrids to the entry closet she vacated to permit me to install my audio equipment rack there. If you're at all familiar with Fulton Gold (I swear it's robust enough to hold up the Golden Gate Bridge at rush hour), you know that was a major "give" on her part, and I knew then and there that she was a keeper.

This time around, as she settled into the listening position for the first test of the "new bedroom decor"--and before I put any music on--she said after a few moments of conversation, "It's quieter in here." Yep. And after listening for a couple of minutes to a 16/44 rip of the Turtle Creek Chorale singing Lenny Bernstein's "Make Our Garden Grow" on Reference Recordings' "Testament", she noted the vocal articulation and ensemble layering discernible with the panels installed. "As soon as I can find a place for them, I'll take the jewel cases out."

Being able to use panels from the main system to test the bedroom configuration proved to be indispensable in at least one respect. It allowed me to compare the use of full-range 244's with their scatter-plated cousins at the rear corners. I wasn't sure I'd hear much, if any, difference, given my listening location about only four feet in front of the plane of the scatter plates. I tried the full-ranges first, then listened to the scatter-plate iterations, and then went through the whole this-first-then-that routine again with a variety of ripped and downloaded program material. With the full-range 244's it sounded good. With the scatter plates, the presentations sounded a touch more open and--where such information was embedded in the recording--"airier". There was nothing subjectively exaggerated about the latter characteristic, and, overall, the scatter-plate-configured presentation sounded a tad more "real". So that's why the scatter-plate 244's still hang there.

I've ordered the replacement traps in "cash-flow" stages. A new pair of full-range 244's constitute the first-reflection-point panels seen in the photos. A scatter-plated pair is due in this coming Thursday, and the final pair of full-range 244's should arrive a week from Monday. I'll follow up with the Monsters shortly thereafter. The sonic results render them more than well worth the investment.
