What's most important?


I had some friends over last night, and we started to discuss the different things that go into assembling a high quality stereo playback system. The level of disagreement, and the heated discourse, was both fun and surprising. Here is what I think, in order from most important, to least: 1).THE ROOM/SPEAKER INTERFACE- choosing the right speaker, and placing it properly in an acoustically "sound" room with a dedicated power line. If this is wrong (like a Wilson Grand Slamm in 12 x 12 x 8 room) well, then why bother with the rest. 2). THE SPEAKER/AMP INTERFACE- this is a close second, and depending on the circumstances, might even be first. If there is a REAL problem here(like low impedance/sensitivity speakers w/SET amps) nothing else will matter much. 3). THE AMP/PREAMP INTERFACE- again, this seems to be the next place where things can go really wrong in an audio system. 4) SOURCE COMPONENTS- I know, this is lower on my list than most people would like, and I don't mean to infer that source components don't affect the quality of a playback system. Of course they do. I just feel that if the above issues have not been addressed, then simply throwing a reference quality source into the system might not be the best way to maximize the potential of said system. 5). INTERCONNECTS AND SPEAKER WIRE 6). ISOLATON DEVICES, A/C CORDS, POWER CONDITIONERS, AND OTHER VARIOUS TWEAKS.....Well there it is. Again, in an ideal system, ALL of the above issues would (should) be addressed sooner or later. But how would you prioritize things, and why? Release the hounds........Robert K.

I appreciate your views, Eldragon, but I still don't see how the preamp (or integrated amp) can be MORE important than the proper SPEAKER/ROOM INTERFACE. And please notice that I did not say that the SPEAKERS are MORE important than the preamp, but that the INTERACTION between the room and speakers is MORE important. In my friends system described above (Vandersteen, Bryston, Resolution)I used a RTA to help figure out what was going on. He had 10dB rise from about 100Hz to 250Hz, and a 8dB suckout from about 65Hz down to 50Hz (from the flexing of his wood floors, we presume) and allot of other problems through the mid and high frequencies. When we moved the speakers along the long wall, that helped, but nothing changed from the upper bass down. He could never understand what was going on, and tried different amps, source components, and wires. And while each change produced a shift in the spectral balance of the system, nothing really helped to make the system more enjoyable, at least according to him. And after looking at the in-room frequency response plot, I can understand why. He was fighting a problem that could not be solved unless he got new speakers, or a new room. With the Dunlavys we were able to get nearly flat response from about 50Hz to above 10Khz with only a minimum ammount of acoustic treatments. Are the Vandersteens *bad* speakers? Of course not. They were simply the WRONG speaker for this room. And no preamp I know of (besides one that uses digital correction) can compensate for really bad frequency response problems. This is why I still contend that the SPEAKER/ROOM INTERFACE is most important, and by that I mean selecting the right speaker for the proposed listening room, setting it up properly, and applying acoustic treatments if needed. Until my buddies came over last night, I thought this was common knowledge, but boy was I wrong. And please try to remember, I'm not saying that SPEAKERS are MORE important than any other component. I'm simply saying that the SPEAKER/ROOM INTERFACE (as I've defined it in the above posts) is more important than just about anything else, at least in my experience....Robert K.
......I should have also noted that I use 5 ASC tube traps to facilitate speaker/room interaction-- AND I have 3 ASC panel traps on order to deal with side wall reflections. Cheers. Craig
What most important?Everything in a system is important, and that includes your own ears, of course!A system is working in an environment, in which the system in itself, is an integrated part.Where does additional efforts pay divident the most? Of course, one can make statistical investigations, to find out e.g., that room treatment had the best influence by , say 60% of the systems, evaluated by their owners, but that dosen´t nessecerly help you, to make good desicions.I will say that one important thing, among others is one´s ability to analyse problems and strengts in the system. With that, you probably don´t simply trow gear out, and replace it with other gear, in hope of an improvment.Instead, you work towards an end, and if you don´t know how to get further improvments,you consult others, who hopefully knows.Having had this interest,for about 40 years now, and having built many loudspeakers, amplifiers, and done a lot of tweaking,I can say that there is no shortcuts, everything in a system has importance, but many audiophiles have insufficient knowledge about acoustics, electronics, physics,so they are often searching in wain, for improvments.I don´t blame them. And I don´t state that I know enough,I don´t. But with better knowledge one is more resistent to marketing hype, and with experiences one can make more intelligent guesses,e.g. it may be better to improve the power supply of the preamplifier, than to buy new cables.Thus, if it is a single thing that IS most important, I will say knowledge!
Robert...i understand your point! However, we have to first follow some logic here! Before we buy furniture, a rug, HI-FI! We have to have a "space", and that is dedicated, or not, room! Are all rooms built with four walls, ceiling and floor? Yes or no? The size of the room should determine what kind of amplification and ultimately what kind of speakers will be best suited for! For example, rectangular room 20'x 15' moderately furnished (not cluttered)will be perfectly suited for medium-low amplification with large monitors or two-way floorstander! Anything larger, and you will probably run into some problems! Vandersteen are good speakers, but as i understand they do "pump-out" large amount of low freq. And you need relatively large room to enjoy the full potential. Regards!
My idea was that, AFTER the fact, we know (assume) which sistem will be suited for our "environment" that THAN, we build our sistem around the PRE-amp, and not the speakers! Regards! P>S> refer to R. Harley's book, and new "THE INNER Ear" where is interesting article on importance of pre-amp! Dragan
