If anyone wants to know, I am using VPI gear that I modded very much, along with Air Tight PC-1 and my prized Colibri XPW (platinum coils) that I got with about 3 hours on it and it is just breaking in now. There are so many posts that this phono stage cannot be SOTA,even with mods, but I do not agree. It is not that great with standard tubes as a stock unit, but becomes a monster if tweaked properly!
Are there any other EAR 834P modders lately?
I had to beg David Schulte of Upgrade Company to mod my EAR 834P because there are so many detractors. There are also loads of DIY people who have tweaked the circuit in custom ways. The changes I had made include V-cap coupling caps and RFI shileding. Switching from using the 12AX7 tubes to 5751 or 12AT7 tubes if you can handle the lower gain also is highly beneficial. I use Valvo 6201 blue print in the one spot, Brimar and Siemen Halske 12AT7's in the gain stages 2 & 3. 2 is not left and 3 is not right- it sums the tubes for the gain stage left and right. My results are stunning. Because the 12AT7's only have 70% of the gain or the 12AX7, I changed out my Bent Audio step up tranny's for Bob's Devices Cinemag 1131 with a 1:40 or 1:20, ratio which is adjusted at the flip of a toggle switch.
