Primaluna Tube System

Md30, If you want to 'tone' down the highs a bit, you might try some current production Mullard 12AX7's in the pre-amp - if there is no change there you might try them in the amp and see if that makes a difference. If it works in either, you might extend the thought to the other devise and have them in both.

FWIW I'm currently using the Mullards in both of my Dialogue units and they make a difference which is easily audible.

Learsfool, If you are looking for EL34's which are not harsh at all, try the JJ E34L's. I use them in my Dialogue One and they produce an excellent mid range (where all the music resides). :-) Tube depot sells them for 13.99 ea. Doesn't get much cheaper, and they will do a 24hr burn in and matching for 1.50 per tube. I've never tried them in my Two so I really can't predict how they will sound, but I do prefer their tone to my longstand preferred SED EL34 I've used in other amps.

In my Dialogue Two I'm using Tungsol 6550's and the Mullards. With my speakers this produces a nice warm full sound which is both sufficiently revealing AND relaxing. It lets me relax from the audio angst which hangs around my house and just enjoy the music. A winner for me!

I don't find the 12AU positions very critical in Dialogues - I presently use JJ's, EH's, or EI's. Right now I'm using the JJ's.

Hope that helps a bit.

Thank you for the recommendations. I will pick up a pair of the Mullard tubes this weekend. Someone else recommended the Genalex Gold Lion 12AX7 reissue. Might get a pair of them as well and compare them with the Mullards in the preamp.

Now for a bit of a shocker. My mother-in-law heard my stereo a few months ago, and asked me to find her something that would sound "similar," on a minimal budget. So I picked her up a Luxman R-115 a month ago, and tonight I found her some old PSB 400 speakers. Just set up the receiver and speakers for her. Darn the mid-range is wonderfully rich and smooth on this setup, which cost less than $200. Makes me want to replace my Vienna Acoustic Haydn Grand speakers with 3-way, larger bookshelf units. Anyone have recommendations for speakers that match well with the Primaluna? I am seriously tempted to find a more recent version of the PSB 400.

I had a Prologue 3/5 setup two years back now.
They really opened up once I changed the stock tubes to vintage pieces. The only new issue tubes were Gold Lion KT-77's in the Prologue 5.

Al. Wise can you specify which NOS tubes you are using? Thanks.

My best results were using either Sylvania or RCA long plate 12BH7A's in place of the 12AU7's and Telefunken's or Bugle Boy's in the 12AX7 slots.I aslo had good results with Raytheon black plate 5963's, but I liked the 12BH7A's the best.
My best new production 12AX7's were the Black Sable cryo treated Sovetek 12AX7LPS tubes from Tubedepot.
