@paulcreed , I experienced the same faults as you when using the isoacoustics pucks; less air and slower overall. Also lack of transparency. DH Cones has everything I'm looking for; jump factor is a good term to use. Noticeable on preamp and tube amp.
Opinions Golden Sounds DH Cones, I just bought some,they came in today
I bought some Jumbos to go under Preamp. Will try them this weekend, they just came in today. My tube CD player has easy access so I replaced Mapleshade brass with jumbos. I placed them in biggest triangle possible and found them a little exaggerated in the highs. I moved the back two feet 2 or so inches closer together and it smoothed out very nicely. That's as far as I've gotten. Very nice improvement over brass which I swapped back in just to confirm my findings. If you have used the DH cones which component faired the best with the cones? I have amp, Preamp, phono preamp, turntable power supply,. I've heard 2 up 1 down, 2 down 1 up. Any advise were to place under component. I am going to buy Gaia Oreos next anyone compared the two, thank you.

The pucks cleaned things up for me when placing them under the preamp (Jeff Rowland) & dac, as well as under the power supply for both the dac (Audio Alchemy's latest) & phono preamp. I've tried several feet under these (including the DH cones) & prefer the pucks. In my case, they improved imaging & detail better than the others. |
I'm going to put pucks back in and see if they settle in and leave them in for a week or so. I don't want to give up on them yet, I have 30 days. I'm putting them under a Bruce Moore Preamp with Jupiter copper foil signal caps and Duelund bypass caps. The preamp is very smooth and transparent, maybe its too laid back to match with pucks who knows. I did pull in to a industrial supply today on the way home from work and bought .750 and 1 inch diameter springs ground down ends flat so they don't wobble and stuck under CD player platform in place of spikes with DH cones under player. Will see what they do for hell of it. I did listen for first 5 minutes while everything was cold, maybe Im crazy but sounds like things may sound bigger/larger, I could be hearing things. I will listen later tonight see what happens. |
Boxer what is the weight of your preamp and which pucks did you purchase. My Preamp only weighs 15 pounds and I found it sounds better with 3 mini pucks which is rated at 6 pounds each. Seem like I'm pushing it to the limits. Maybe I'll try 4 pucks and let it settle seems like that would be better weight ratio. |
I use 3 pucks under my preamp as well. The pucks I'm using are good for 20 pounds each. See link below. My guess is the preamp weighs around 35 lbs. FWIW, they do say to have the logo pointing toward the front (in other words, toward you). Not sure if it makes a difference or not, but that is how I've always positioned them. http://www.isoacoustics.com/iso-puck/ |
