It May Have Been... & Which is Better???
I think one of the reasons I was so impressed with the PF XCAN v3 "in it's final days" were the effects of the OPA2134 in my modded CD25 1+, as well as the X10 v3 Tube Buffer, and the XPSU v3 PSU - they synergies between all of those units with my Senns.
I just didn't notice it previously, because I hadn't used that combination of components much, since I swapped to the OPA2134s in the CDP - they made a huge improvement over the dual OPA627s, or the OPA2227s.
I just tried the X10 v3 with my DV332, and it does add much of the same qualities that my PF XCAN v3 reflected in its final days, when driven by my moddifed CD25 1+... but... with more power, drive, weight, etc.
Now... I'm wondering if the Yaqin Tube Buffer would improve the DV332 even more. I realize Godkin uses these together, which is one reason he is so impressed with the DV332, compared to the XCAN v3. And... I realize from prior posts, he prefers the Yaqin Tube Buffer to the X10 v3.
But... if I were going to try the Yaqin Tube Buffer with my DV332... which one should I try - the version with the single 6DJ8 / 6922 tube, or the version with the two 6J1 / 6AK5 tubes???
One vendor says the single tube is the newer and better unit, and another says the dual tube version is the newer and better version.
So which is better???
