Well it's pretty simple in my view, he states the outboard power supply made very little difference when plugged into the preamp on the top (same brand). But made a 30% guesstimated improvement with the preamp on the bottom. The top preamp has a well-designed power supply the preamp on the bottom not so much! So sure it can...if the gear is crap in the power supply department!

Okay I went ahead splurged picked up a pair 500-SA mounted them up high on the front wall. Seems to work darn nice... My sub seems to now be my weak point. My 2002 era KSW-15 is just to slow blubbery to mate well with the Belles and the rest of my speakers.. I was digging around Amazon and eBay the Reference R-12SW can be had cheap! The review I've read all seem great many call it tight, articulate and distortion free. At $200 each affording a pair is pretty darn easy! Any thoughts?

👍Do you have 4 extras lying around you want to donate? 😁

What the heck are you doing around here? I seem to recall you saying "a cold day in hell" LOL!!!

Thanks! Not sure I just know they need to be efficient enough to be level match by the available adjustment in the receiver. The timber match I would think is secondary. Which is really what my question was about since Klipsch does not list that spec. only that they are Dolby Atmos compatible or compliant.

I found a newer manual that I believe states you can do rear surrounds or Dolby Atmos height front not both. It actual spans 3 pages talkiing about speaker hookup and Dolby Atmos. So I guess I just saved buying 2 of the 4 I was thinking about.

Thanks everyone. Wuzzzer my ceiling is at an extreme slope (cathedral) with the lowest (8ft) wall on the right side of the room and the highest (about 16' to 18') on the left. So ceiling mounting or firing them up is not possible. I was considering doing 4 of them. Two mounted flat about 10 to 12' up on the front wall pointed downward toward the sweet spot and another pair up just under 8' on the right and left walls angle to or near the listening position. I'm just spit balling rioght now since I'm current laid up with a bum knee.. health wise the hits just keep coming nothing life threatening, just annoying as all get out. Check out the attached picture of the page with speaker hookup and layout gopt the TX-NR636 receiver it looks to me like they have you wire the front and rear height speakers in Parallel per channel. PS the manual is dated...at the time of publish I do not believe Atmos was supported or maybe even in existance. It was added through firmware update so the drawing might be useless since they do not refer to the rears as height speakers. .

Been I while since I've posted around here. I was looking for some idea of the efficiency of the various Atmos Elevation speakers Klipsch offers. Like the R-104SA, R-40SA R-41SA or RP-500SA. Stating complies with dobly atmos doesn't tell me much LOL!! I'm trying to decide if they will at all blend intyo my al;ready none comforming surround setup. I'm using Belle Klipsch as the mains, KLF-C7 center and Heresy rears. Was thinking about adding sides and 4 atmos up firing since my Onkyo TX-NR636 Receiver supports it. It has + - 12db for level matching so I can lower fronts and center to match the Heresy's and raise the elevationb speakers to meet that. What do the home theater gods have to say? Thanks Craig

I'm watching you!

This amp was my own personal stereo VRD that someone talked me into selling to them... Trust Paul I don't believe anyone on the planet has tried more tubes in VRD's that included me. In the end you'll never go wrong with any "VINTAGE EURO Made" Mullard or Amperex in either the AX7 and AU7 slot.

👍 or the reverse.....well unless your a fan of distortion. These types of suggestions usual have an origin in guitar amp circles where distortion is king! Not at all advisable in the Hi Fi tube amp.

Yeah that looks special alright.... a brief peak gives me a chronic headache..

Christ I figured COVID took you out! Yeah I always have had trouble letting go LOL!!

Yeah someone around here was nice enough to send me a manual for a MC2000 these later year 4 or more tube per channel McIntosh amps have bias controls and test points. The vintage models I'm used to working on could have been modified to do the same but that would be a sin to any true McIntosh lover With these newer units only being around 20 years old I serious doubt many have needed repair McIntosh amps are really reliable even the vintage ones will keep working and working long after they should be for there own good!

Self bias takes care of tube drift? Please explain how it does that continoulsy?
