PrimaLuna ProLogue One versus Two

Vincedog3,
Just ordered my Primaluna Prologue Two today. Any breakin
suggestions, or were you impressed out of the box?
I'm also thinking about getting the Njoe Tjoeb 4000 cdp.
Any thoughts on that plan?
Thanks,

Any comparisons to a dynaco St-70 stock or modified as I have both and I am thinking of a primaluna

Thanks guys for all the kind words. I can't tell you how happy it makes me to see the reaction from people that really feel like they got something for their money.

Tube rolling:

The manuals I think are pretty nifty (I wrote most of it for the English market). The ProLogue one is best to stay with EL-34. We don't want to represent going to 6550/KT88 is OK.

The ProLogue Two can go to EL-34 should you decide to. In fact...the Adaptive AutoBias is so "smart" that if you broke a KT88 and did not have one, you can use an EL-34 until you get a replacement! It adjusts!

In the 12AU7 position, you do not have to get the highest testing tubes as they are the driver. So if you want...save some bucks.

The 12AX7 has a more important roll, so a low noise tube is preferred for best performance. But because it has a nice quiet filament supply, it won't be as picky as some cheap-o stuff I won't mention. (The cheap-o stuff costs 2.5 times the PrimaLuna price by the way)

You may want to try the 1961 Sylvania 12AX7. They are nifty and reasonable. Want sexy? Try Mullard CV4004.

The message it you can scale the heights...but if budget conscious there are no worries. The tubes are run easy. No components, including tubes, are stressed. It is fuse protected.

Lastly...giving an honest opinion is nice on chat or better yet review forums. It helps us keep the price low. I ask a lot of folks to take the bottom plate off the amp to see how it's built. I hope you do.

Cheers to all of you

For those of you who asked about tube rolling - I have had a One for 2 months now and have changed out the EL34's, the 12AX7's and the 12AU7's, trying various combinations. They all make a meaningful, and readily apparent change in the sound of this unit - you really can tune it quite easily to get the sound you would like. I'm sure this would work for the Two as well.

My suggestion for those of you with limited tube experience - before you get caught up in buying expensive NOS tubes do some research on the tube types and the sound attributed to the various current production brands. Its a cheap way of getting some valuable experience - eventually you can move on to some NOS stuff but I think some of you will be surprised at how good these units can sound with good quality new production tubes. Audio Asylum's tube forum is a good source of info as is Job's Tube Lore in the AA FAQ's.

Vincedog3:

I highly recommend the SuperTjoeb 4000 (with upsampling) especially with upgraded tubes from Kevin Deal's secret stash, e.g., Ediswans. You'll love it!

Best wishes,
Lou
