What's next for the ultimate sound quality?

The question may be naive, but I'm not sure what's next to try in the quest for the ultimate sound. I owned the entry level magnepans mmg (didn't like them much for anything but jazz), monitor audio S6 (good all around, imho, but nothing spectacular except for the cheap price tag). Lately I built speakers myself that should supposedly rival the best in the world (ZRT 2.5 from Zaph Audio with Scanspeak drivers)

(design):

actual speakers:

The question is what's next? These speakers use one of the best drivers in the world and the best I've heard to date with excellent bass and accurate sound, but soundstage and imaging could be improved (magnepans are better). Also, the sound is a little thin. Am I asking too much, though, from 2 wooden boxes with paper diaphragms in the middle? The speakers are built precisely up to spec and I'm pretty sure that's the way they should sound.

Have I reached the limit where the speakers should be left alone and improving other components can make better returns; e.g, room acoustics and/or amplifier not to mention using quality recordings?

P.S. The receiver I'm currently using is Panasonic SA57 connected to a computer via digital COAX cable and JULI@ sound card. Despite the cheap price, this receiver is great, imho, and sounds better than my NAD 754 (probably because Panasonic is on the bright side and the speakers are warm, so it pairs with them better).

Thanks!
Gleb.

Shadorne, you got it! The sound is indeed clean, detailed and punchy and slightly damped.

Given my ideal sound description (a wall of clean and powerful sound), I've got clean and powerful, but the "wall" is missing.

Is tube amp the right answer? There seem to be a lot of DIY designs for tube amps. Or should the room acoustics be dealt with first? Thanks!

Your room looks very "bright" hardwood floors and bare walls. I'd get an area rug on the floor and acoustic panels on both front and back walls and the 1st reflection point on the side walls and then see how it sounds!

S7horton,

Right, I'm quite a newbie and haven't had a lot of opportunity to experiment. In fact, very little. Before building these speakers, and having listened to Seas drivers for 3-4 years (in monitor audio speakers), I bought drivers from Aurum Cantus, Bohlender Graebener and Scanspeak (for reference planning to return them later). After auditioning, the scanspeak tweeter came so on top that I really decided to build a reference system and not waste time and money on everything in between. In terms of amplifiers/receivers, Panasonic and NAD are the only ones I've got and Panasonic sounds better with these speakers. NAD was wonderful with Magnepans.

In terms of "thin", English is not my native language, so this may be a confusion on my part. "Damped" may be a better description. If I put studio headphones to compare the sound (I have AKG 271), it's pretty much the same except that with the headphones, it feels like there are more instruments playing (thin, damped?) and the speakers have more realistic bass and highs.

P.S. How does one experiment with amplifiers/receivers anyway? Do you buy a receiver and return it if you don't like it? Or bring your speakers to the dealer?

That's what audiogon is for. Figure out what you want, buy it used, and sell it later for small or no loss if you don't like it.

In my opinion, those speakers deserve better than a reciever. Something like a really nice integrated, or a separate pre amp and power amp.

I do not think a tube amp is the answer. I think better quality solid state along with proper placement, and room treatments is the answer.

Are your speakers uncluttered well away from any side walls or furniture? Any sharp edge obstructions can kill soundstage. 2 feet minimum and 4 feet is best. Also - is your listening position away from any walls - this can kill soundstage too.
