In Reply to: RE: Parts Changes to Improve Imaging? posted by Awe-d-o-file on April 18, 2018 at 05:03:08
Thanks Awe-d-o-file.
I am pretty satisfied with my AC power situation. Am running all power thru a big iso transformer with separate (but same phase) legs out for digital and analog then to sub panel and separate breaker to each component connected via 7 feet of silver clad 10 and 7AWG. Also have "Felix" AC filters in DAC and in Server. The efforts in AC resulted in good improvements-- but not in imaging. But perhaps laid the groundwork for it?
What have you found effective in the way of component isolation? I currently have everything on spikes and wood cutting boards.
Funny you mention the three tweaks. I am currently experimenting with all three! In my system I found subtle improvement with the ground tweak and speaker filters. The battery tweak I have given up on. Am currently putting together the refined versions of the ground effect loops and the speaker filters, hopefully they will give me more dramatic results.
Also want to try a capacitor or capacitor + litz loop in place of only litz loop. It was mentioned by BudP once or twice but he could not specify the exact recipe. Bud mentioned using a cap "under 20pf". Meanwhile a guy in Hong Kong found that the bigger the value cap the better.
Follow Ups:
"7 feet of silver clad 10 and 7AWG." +10 Now you talkin' my kinda language. I actually had 4awg at one point back in a previous audiofool life on an amp. Like I always say, bigger is always better, much of the time. An inexpensive experiment would be to get three real like 5/8th inch solid brass acorn nuts to uses under an amp to give you an idea of what brass would sound like. Not plated. Brass is my fave so far. They beat Black Diamond racing cones IMO, which were product of the year at some point if I remember correctly. If you like that I have every reason to believe that bigger is better and that points on brass footers are better. Mapleshade has a number of likely great choices if you got the dough. EAR C-1002 is my fav rubber for audio in my experience. Michael Percy carries it. My vibration paradigm is brass,yellow poplar,and the fabuloso EAR C-1002. The EAR is scientifically designed for absorbing vibration. Sounds better than sorbothane and neoprene to my EAR's. With 7awg silver clad, Silmic ll and your recent and upcoming experiments it sure looks to me that you are on the right track. Let me know if you have any of that 7AWG stuff cluttering up you house that you are dying to get rid of. T456

Sorry! I must confess I dont actually have any 7AWG silver clad. I should have said 7AWG "equivalent" in that I just doubled up the 10 gauge on the run going to the amp. Wow, 4 gauge?
Yeah we are thinking in the same neighborhood! I currently have brass cones bolted in place of the feet on all electronics except the server. (Kinda want to isolate that as it has hard drives spinning constantly and vibrates.) And BIG brass spike/footers mounted on the speakers. (They are Mapleshade clones.). Everything sits on a cutting board then a cupboard/shelf unit built into the wall. Under the speakers and their maple cutting boards is granite. But just between you and me, I'm not sure I hear much difference due to the all that brass and wood (looks serious though!)
I take it you have all your stuff on brass cones then on yellow poplar? So where do you use the EAR C-1002?
EAR is under the wood. If you ever order from Percy it looks like he has 6.5 x 6 in. 1/4 inch thick pieces for $7.50. You could make a tripod from that to test the stuff. I'd clean it with alcohol first and not put it on any surface that you don't want discolored without using something like plastic wrap. I use it under the yellow poplar. I would suggest listening to 3/4 in. yellow poplar in comparison to whatever wood you are using. I'm not so sure the granite is helping sound wise. As to not hearing much difference with brass I'd try taking it out and listening and putting it back in. If these produce only subtle and not real important differences to you maybe the EAR wouldn't be so remarkable. Herbies Audio Lab agrees with me on the yellow poplar being good. Every wood I've tried sounds different. Yellow poplar won my contest. T456

Ok thanks. I was following (I think it was) Mapleshade recommendations to use spikes from equipment to wood and then more spikes between wood and substrate. Good way to sell spikes, I guess.....
However, I ended up going the same direction as you. Now using a rubber gasket material between wood and substrate on all the electronics. However, still have spikes between the wood that the speakers sit on and the granite.
I agree, the granite might be a bit dodgy. But I liked the idea of sinking the vibration into mass. And hoping that big ol' 15x20 by 3" thick block of maple in between speaker and granite is mitigating any bad vibes?
Perhaps my next move in the vibration arena will be to experiment with pulling the spikes from the wood under the speakers and replace with something to soak up vibes. I do have some sorbothane on hand so will probably start with that. If its success, will seek out some EAR.
Also I'll have to see if I can find some Yellow Poplar here in CO and play with it a bit.
My experiment with random maple, not special superduper maple, just a random piece of maple was that it was musical but sucked out dynamics. If I remember correctly someone else corroborated my perception on AA. Wood has a yuuuugggg effect on sound and once again I question that thicker is better in this one area. Yellow poplar isn't really poplar and is very common in large hardware stores, at least around here. Tweak on. T456

Congrats on getting rid of those output caps!!! It's revelatory, IMO. Oddly enough I found that 3/4 inch yellow poplar sounded better than thicker , like maybe two or three inches. Wood is the mass for the brass cones. Only getting rid of the granite and listening will let you know for sure. The best idea is the one that sounds the best. I guess you'll have to find another place to test your new caps. I was hoping for the magic .01 in my dac PS to give me the most cavernous depth. Might have to buy some new binoculears after your report. While you're at it you might consider replacing some of that really tiny hookup wire with the 18AWG if you want to further improve the sound. Even better would be to replace all of it. A no brainer in Tweaker's World. T456
