I wrote a drawn out peice on the two channel about the minimax threesome. heres what pertains to the phono:
I started the audition by hooking up both the EAR and MiniMax both with the stock tubes and played several albums. Joe Jacksons body and Soul was the first. I had a tough time on a clear winner because they seem to have they're own signatures the 834p had a bit lushness and the EE had better extension on both ends after four or five album sides It was clear that the EE was more detailed and had a deeper stage . It wasn't until I swapped some tubes that I notice a sizable difference. The first tube I swapped was the Gain stage (center) I placed a old stock RCA ribbed short gray plate. the liquid mids that the EAR had was now shining through on the Mini. That's it, this is my new stage. A friend tube dealer came over and we tried several tubes. The Winners in descending order are:
French made Amperex 6X4
Dutch (amperex) HP 12AX7 Primary gain
USA RCA 7025
This line up was best for my taste in music , the bottom was stronger than anything I tried while not being bloated. Steve Millers fly like an eagle is bass heavy and it sounded like I had added a sub , the new REM had a wonderful presence not heard in this system before and Dusty Springfield made me think I was the preachers son.
The Amperex 12AX7 edged out the Tele. smooth plates but not by enough to justify the added expense at this time. Either set would second place. I thought the biggest difference was a bit of sweetness giving the illusion of more detail. I'll pick them up sooner or later.
The RCA 12AX7 in the center with the Telefunken (smooth) on the outside was my fourth choice . Depth, space as well as a tight bass were all there but needed a bit of Air to top the the others.
I didn't notice as much of a change in the 6X4 as I had expected from the stock JAN to the Amperex perhaps the recommended Tungsol is in order. I would go with the RCA, TELE, or Amperex in the primary gain to get the most bang for the buck. Ive read that the Groove tube 12AX 7 is a nice and inexpensive alternative but have yet to try it .
Thanks to those who took the time to read my ramblings and feel free to ask questions if you have any . Just my .07
