In Reply to: Oyaide R1 AC Outlet Report posted by Duster on April 10, 2007 at 12:40:46:
I visited inmate MikeL's place last night (http://cgi.audioasylum.com/systems/663.html) to listen to the Oyaide R1. Mike reported for himself as a response over on Tweakers' (http://www.audioasylum.com/audio/tweaks/messages/143731.html)
As luck would have it the first thing I listened to (a Shaggy SACD) showed the least difference of anything we listened to :) In fact I didn't like the differences in bass response at all at first blush, BUT as we played other things the blacker background's effects became much more obvious and we really enjoyed the additional detail that was apparent with the R1 in everything we played: sometimes more texture in the bass, more detail in cymbals, longer decays and especially in good acoustic recordings: more room ambiance which really added the the sense of being there. Also the soundstage was deeper and wider, something that was even less expected :) Compared to the cost of some other things I've done to my system these seem like a bargain.
..by MikeL's audio set up.
Given his sound room custom design-built by whatever professionals,
he knows the way to set up his gears properly.
With the front loudspeakers far enough from the back & side walls,
virtually nothing in between the pair the loudspeakers & the sweet spot - no coffee table etc etc piled up as commonly seen, it provides an unobstructed free acoustical corridor for direct & first reflected soundwaves.
One excellent thing I have to mention is the music sofeware are all
put away from the frontal area. This surely eliminate irregular deflection of the soundwaves.
Only thing I think I would do is to move the power amp from the speaker centre location back to the audio rack. Longer (but equal lengths) of speaker cables do far less damage to the sound than long ICs. This also clear up the little acoustical mess in the frontal sound corridor.
One suggestion which may provide better sound still is to move the audio rack a bit further back beyond the sweet spot & cover it up from some woolen sheets to eliminate any controlled reflections.
Incidentally, my basement audio den bears similar acoustic layout - with complete clear-out front sound corridor. Hard smooth reflective back & side walls throughout (thin plywood board with wooden studs & voids behind all over along the concrete structural walls of the basement). Wall-to-wall Drop ceiling with standard fiberglass acoustical tiles, & wall-to-wall carpet with cushion underlay.
Only 7ft ceiling clearance, it got no ringing up to 120dB peak SPLs.
Was this outlet changed out while you were there?
No offense, really, but the title line of your post is 'interesting'.
Mike had some of his dedicate lines redone with the R1 and faceplate, he also kept some on the old outlets for easy comparisons. He's been running them in for a while. We went back and forth from his old Jena Labs outlets to the R1's a couple of times. It's always great to visit Mike so I take every opportunity and I'm very familiar with his system. (Also we have the same transport and DAC.) I brought my own music as well as letting him put on the music that he's found that shows the differences off the most.
I hope this answers some of your questions :)
