Paging Jeff...EAR 834p caps quesion
« on: 19 Mar 2019, 11:04 am »
Hey guys. I'm new here at AC forums. I fell on here from the Google machine that led me to https://www.audiocircle.com/index.php?topic=157930.0 this link. It look like Jeff helped a member out with exactly the information I'm looking for.

I read the Thorston http://db.audioasylum.com/cgi/m.mpl?forum=vinyl&n=108318 EAR upgrade and it got me really excited to do it. The issue is that I don't fully understand part of it, I'm having real trouble finding the right caps, and I'm not sure what I can stuff in the EAR case.

Will someone help me?

Jeff

I have an EAR 864 preamp, which includes an 834p phono stage. I used Rel RT polystyrene caps on the phono stage many years ago and it was a noticeable improvement over the stock caps (I think they were Orange Drops). The line stage also had Orange Drops, but I changed those with V-Caps (tinfoil) at about the same time. Spatial information was improved. High frequencies were more detailed and clear. However, over time and with different monitors, I found them fatiguing.

A few weeks ago I opened her up again and removed the V-Caps and put Miflex KPCU-1 in their place. I got the idea when reading through the Troels Gravesen website. I believe he used Jupiter caps, but of a design with similar ingredients. (Wax/Copper Foil/Oil/Polypropylene)

The end result was beyond what I had hoped for. Plenty of spatial information, deeper and wider soundstage. Low frequencies were bigger, heftier , fulsome and dynamic. The perceived frequency response was more balanced.

I recommend the Miflex if this is the sound you are after.

If I had to characterize the Rel RT Polystyrene, I would say that they are clean and very clear. Lacking glare or dullness. Well balanced. Perhaps a bit dry. I hope this doesn't sound too weird, but polystyrene has a neutral resonance, not unlike rubbing a Styrofoam cup.
