All of his cables have what I would call less is better as one of the concepts. Especially the IC's. Interestingly they therefore have little or no break in time. The first hour and the 50th hour sounded the same to me.

The posters on this forum have been so helpful to me in my recent return to music. I want to offer my recent experience as a partial payback. Paul Speltz's anti-cables brought my ARC components, Rotel amp, and RF 7's to life. I love great stuff at truely bargain prices and his latest entry into IC's gave me fantastic sound improvement over the 18 year old MIT shotgun interconnects I was using. My MIT's still sounded good but his IC's blew them away. My MIT's cost me $550 and $350. The anti-IC's at the introductory price of $50, are in very limited supply and not on his web site yet. As George Foreman says, "you don't pay a lot but you get a lot". I have no connection to Paul. BTW the speaker cables are $10/foot for the pair. I did a DIY 7' biwire in 3 hours at a cost of $70. S&H was free. Got the cables in 2 days. Now I can just listen, listen with a BIG SMILE on my face. My pure guess is those IC's will not be at $50 long. If you snooze you may have to pay more. Finally, thanks again for all the help in getting me back on board!!!

Dean, I don't understand crossovers very much but is The RF 7 crossover low order first or is it high order 4th?
-
I a novice, understand it this way. The braided cat 5's are high in capacitance. This can cause some amps to ossilate at around 30 kilohertz which is inaudable.The amp gets hot and self-distructs in time. The ossilation is sort of like shrill feedback build up on a microphone. The Zobel goes from + to - at the speaker, and dampens this ossilation. Do a search on Zobel on audio asylum "cable Forum". I have recently learned a lot there.
-
Even if you have the original boxes, shipping them could give you a nightmare. Buyer pick-up or you deliver. Same with getting the RF 7's.
-
Dave, before you connect them, I strongly suggest you put a Zobel at each speaker. Two at each speaker if you bi-wired. No matter what speakers or amp you have!!! What Belden cable # did you use and what connectors?
-
Anyone try CAT 5 braided cables or other high capacitance speaker cable with Rotel power amps or RF 7's or both Rotel and RF 7's? With or without a Zobel network?
-
Well the Rotel made a crack in the hot side speaker and is now dead in the water=no more sound either speaker. All fuses still in tact. Any recommendations on where to repair close to Pittsburgh-Butler Pa. There is good ventilation around the amp.
-
I am also noticing that the left side of the amp is much hotter than the right. It was not like this before!
-
I have a Rotel 200w/ch power amp which has been running warm to the touch very nicely. It has a built in protection feature which shut itself off. I felt it and it was too hot to keep your hand on it. I turned it completely off and when it cooled back down too a normal warm, and turned it back on and it is running again with a large fan blowing on it. It has no internal fans. Can you suggest a source for this sudden heat? Is something about to fail and this is a precursor? The sound is still terrific.
-
I have owned both and loved both. The RF 7's get my vote due to ease of placement. The Khorns must be in the corners period. A second consideration is getting either to your home in one piece. These are both heavy. The seller must deliver himself or you must pick them up to minimize damage. I would try very hard to buy used in excellent condition whichever and pick them up from the seller. That limits who you can buy them from. Original boxes for Khorns are very important for shipping. Email me if you want to discuss further.

For those of you that have installed Barry's siesmic isolation DIY, what improvements did you percieve and on what components? < DIY=ball bearings in cups on a board supported on a slightly inflated inner tube>

Absolute PC is made in China for GTT audio and video. www.gttgroup.com GTT is a large very high end audio dealer.

How does this PC compare to other after market PC's

Let's take a poll. Who on carpet had better system sound on spikes vs no spikes? Same question for hardwood floors?
-
First, I never put the feet on because I did not have room for the feet. I only have info on spikes and no spikes on carpet. Second, to put spikes on hardwood floor, put down coins as in US coins first. I have no info on which sounds better but as you try both you won't scratch the floor. BTW spikes make moving the speakers VERY hard to do on carpet.
-
The difference was most noticeable on a long drum solo where the drummer is hitting at times the various drums/symbols etc. Everything sounds tighter more distinct in the entire drum set frequency ranges. BTW I was listening to Sheffield Labs Drum CD for component testing and evaluation but any WELL RECORDED comprehensive drum solo should show you the difference.
-
Lay the RF 7 down and to your surprise there are four threaded inserts there with the legs removed. It was a pleasant surprise to me also!
-
I just put the speaker spikes on. They were just sitting on carpet with no legs for the first month. Now they are on the spikes without the legs. Noticeable improvement!!! Has anyone else done this and heard the improvement?
-
Kathy, when you try the Home Depot cable, get enough to bi-wire. If Home Depot sounds as good or better, please don't assume you are done!!! But do take the ones you got back! A lady of your caliber and intensity is not one to assume Home Depot is it. I'm getting ready to make DIY CAT 5 after trying a few other bi-wires. It's your room/acustics, and your ears. Only you can decide as you have recently done with your RF-7's. Home Depot may be it but it may not be FOR YOU!!!
-
Thanks for your post on RF-7's. Also what speaker cable are you using?
-
Does anyone have Jon's CURRENT E-mail?
-
Where can I get wide slotted spades that are not real expensive? The binding posts on RF-7's are fat and on My Rotel SS amp even fatter. It's as if the post and spade makers have never talked to each other.
-
Let me clarify my question. Starting bid set by seller is $10. No reserve. There is one bid showing at $10. Did that bidder bid $10 or could the bid have been higher but only the $10 shows? Thanks for the response above. That's good to know as well!
Anti-cable speaker cables and yes now IC's.
