KvH,
I worked in a couple of audio stores after I got out of college. That was twenty years ago and were I really became a geek.

I am not buying that jagged edge thing. I agree that there must exist quantization noise when digitally sampling any signal and also admit that at the higher frequencies it is worse. What I don't agree with is whether it is audibly different from the original sample. My ears were tested by audiometry to reliably hear up to 21kHz. You'd need to be able to hear reliably above 22050 Hz to be able to hear that noise. The digital if done properly will always be more faithful to the original than analog. What sounds better is subjective. Most people like the distorted analog sound because they are used to it. That's my 2 cents[size=1]D3/\/7YCR4CK3R

KvH:
A VERY small Mid-to-High end audio shop in one of America's faceless malls.
I LOVED it, but had to enter the twelve-step program for sound addicts in order to support my family. But the PROBLEM is, it did give me a background in the language (particularly the modifiers--adjectives, adverbs and such) of technology...and the same game exists in Computers. Let the buyer beware, and read every word if you are going to fall into the trap of spec comparisons!

I've been reading this thread and stayed out of it... although KvH and I agree on some facts. If one wishes to use expletives, hit me! I've been there, done that too (Hey my first love was/is speaker design)
B&W's are some of the finest made... (Mod'd DQ10 are great!) but to another point, many don't enjoy music flat, clean and clear! The (improper) use of equalizers always astounds me, why people always boost and not cut? Because they don't know how to compensate for abnormalities correctly. Case in point, when ever any soundtrack is louder it sounds better to the average person, that is until they hear it properly (ie compensated)! Ones ear must be edjucated for this to happen and once it does, you'll begin to hear the flaws in the original soundtrack (with approiate equipment of course)
Most revelant aspect of High Q vs Low Q speakers (B&W 801's were low Q ~.7, similar to transmission line designs) produce the cleanest bass, tightest, purest bass, whereas the masses prefer Higher Q designs (more boom, Q of ~1.4 or (way!) greater) like Cerwin Vega's. This is because of design influences, Rock & Pop vs Classical/Jazz that the intendended speaker was marketed for. Matched preamps/amps/speakers is a limited point. If the speaker isn't properly compensated for (zobel) it'll do as it pleases, reguardless of the Quality (Q/dampening) of the Amp. Another point is crossovers typically induce gross amounts of phase distortion.
Bottom line is this... The speaker is the final link, you get what you pay for/what your looking for. They produce the most distortion (bass distortion typically exceeds 10%!). Buy what you want, get what you hear is personally better. But if I hear another person claim Bose is best, I'll puke!"Be who you are and say what you feel, because those who mind don't matter, and those who matter don't mind." -- Dr. Seuss

Greebe,
Glad to see another speaker builder here. My DQ 10's are modified, of course. The standard stuff - mirror imaged, mylar caps. Got the sub, too. Had to put in a new woofer when the old one rotted away. i put in an 8" Audax and its not very good. Got any suggestions on a good 10" for the main. I'm thinking SEAS.
I also built a small pair two years ago which my daughter uses. 6.5" and 1" Vifa's with 1st order Xovers. I tried a ported cabinet and didn't get the bass quite right.

P.S. That's why I have the Radio Shack SPL meter that I used for the measurements earlier in this thread.AMD K6III-450; Epox EP-MVP3G5; G400DH32; Maxtor 10gig UDMA66; 128meg PC100; Aureal SQ2500 sound; PCI Modem Blaster; Linksys 10/100 NIC; Mag 800V 19"; AL ACS54 4 speaker sound; Logitech wireless mouse; Logitech Wingman Extreme (great for lefties)

Spot on Greebe. I silently and stealthily go into my cousin's room and tone down his eq settings. The problem is that many people aren't used to "flat" music and in fact look on "flat" music as a bad thing. When I defeat the EQ (His Technics DX930 Dolby Digital Receiver sound good without) he complains that it sounds flat. It took years for me to convince him that Realistic SuperTweeters were not the best ever and in fact were unsuited to the system he had at the time. Flat is good. Good clean heavy undistorted bass consistent with the rest of the music is excellent. Some people say I am a bass freak, I disagree, boomy bass causing chestiness in moderately low frequencies is one of the worst things I can hear. To me the Klipsch is a little bright in the 6-16k region so I cut theses frequencies a little in sonique or xmms.[size=1]D3/\/7YCR4CK3R

Right ON!
Listen to Greebe & DentyCracker guys!!!
They most curtain knows apples from oranges!
They get my vote for being objective, sincere and well arguemented!
And my problem is that I cannot afford to replace my old Cervin Vega boom boxes to something that reproduces the sound more correct.
Ghydda, tried many things, currently using active filter insted of the original passive ones (it did improve things, but not nearly enough).As I always say: You can get more with a kind word and a 2-by-4 than you can with just a kind word.

RAB, I'm thinking Dynaudio, like the 24w100's or 30w100's. They're rather expensive, but the highest quality bass (subs) drivers made. They also boast the lowest THD and IMD of ANY made! I'm sure they'll please you
Another good source is Zalytron.
The guys @ {url=http://www.madisound.com]Madisound[/url] are top notch! And can answer most any Q you could possibly throw at them.
Denty, ROFL I've done that and get the same responceKlipsch's are rather bright in the uppermidrange.
Ghydda, the reason for the boomyness (what a word) is the cabinet's to small... but you could try detuning the port by increasing it's length. This will lower the port freq and shift it below system resonance, thus reducing that darn boom. Try using a "Pringles" can if it's the same diameter!"Be who you are and say what you feel, because those who mind don't matter, and those who matter don't mind." -- Dr. Seuss

Of course Greebe, I went out of business giving advice to cut instead of boost when using EQ's.
Oh, Well, it's only the truth, even if folks can't believe their ears.
I used to use one of those Advent speaker comparators that compared speakers at equal sound pressure levels rather than the same volume settings--folks wouldn't trust it though. Even after in home lessons on the proper use of an EQ, I'd come back later to find the usual 'smile' setting, or every slider jammed to the top.

To respond to Elemental_DH's question about Polk Audio...
My office just got 3 PC's (2 HPs and one Compaq...) with the Polk 2-speaker kit.... They sound really good... so good, in fact, that I traded my old PCWorks and am using the 2-speaker set that the office did not even hook up (I work in a temp agency, and this is a PC for the temps to test on, so no need for the speakers. We have others... some PMPO crap, if they need 'em....).
I'm actually thinking hard about getting the 3 speaker kit (with sub) and doing my surround with Polk, instead of going for the Klipsch...
So that's my answer.....
... and here's my new .sig (sans speakers, though....). Drop by the new Monster thread in The Box if you want the whole story about this...
