Can I get my Prima Luna to sound more like a SET/300B?


 

Dear Audiogon community, 

 

I am ruminating on my current state of mind with this alchemy… 

 

I have spent the past year upgrading my main system to a relatively glorious state… details below and in my profile. 

 

I am at times in the sublime musical hallucination I seek. However I admittedly may be coming to the realization that the sound I yearn for in my heart may be ultimately obtained through a SET or 300B type of solution. And to get there I may need a 5-9K indulgence, in order to match the Nagra Streamer, Holo Audio DAC, and Pure Audio Project Duet Horn’s. 

 

This is something that may take a while for me to enact… 

 

SOOOO…. In the meantime…. What if anything can I do with the amp that I currently have, a Prima Luna Dialogue Premium HP, to obtain a completely enveloping, immediate, effortless, sublime, vivid, and delicious delivery of acoustic, jazz, classical, vocals, horns, strings, cymbals…. Sublime enveloping sensual euphoria…?? 

 

Can I get my Prima Luna to sound like a proper SET or 300B amp? Even close? 

 

Some thoughts: 

-Cap upgrade… Jupiter or Jensen or Duelund or…. 

 

-Main tubes to…. Ray? Mullard E34’s? Psvane PH or UK? Sophia Electric? 

 

(Currently I run Gold Lion KT77’s, which are very nice when they work, but their unreliability is frustrating… in 9 months two go out and one has a high frequency distortion)

 

Or should I bite the bullet and jump in to a serious amp upgrade? 

 

THANK YOU SO MUCH for your brilliant insight… 

 

Cheers to musical alchemy. 

R.

Hello all,

 

I will be spending some time combing over all the information on 300B, SET amps, and the like, and this will take some time! I am looking forward to the potential here… 

 

But yes I read through that thread and I do not disregard the Prima Luna’s potential. 

 

So, considering that my Gold Lion KT77’s are biting the dust, I would like to consider the options you all mentioned as well as ask you all if you have a sense of a few more I have come across as contemporary options:

 

-Psvane EL34PH: These seem possible as an option, though perhaps I seek something with a bit more flair…

 

-NOS RCA 6L6 Black Plates: These seem very pricey and difficult to source in quantities of 8, as my Prima Luna require…

 

-TAD Red Base EL34’s: How are these? I have heard they may surpass a mythical NOS tube… (forget which, from a Satori review of the Psvane)

 

-Ray Tubes: These seem to get written up well, though pricey…. Any personal experience with Ray tubes? 

 

-Sophia Electric: Anyone have experience with these? Supposedly great with acoustic…. 

 

THANK YOU much for your impressions…

SED EL34 from the 90's are best EL34 I've heard. I've had a number of pp and SET amps, closest pp to SET sound I've heard is my newly purchased PP monoblocks based on Bendix 6094 tube, this has 12wpc. I also used to run Prima Luna Dialogue, mods will only take you so far, but some nice EL34 and something like Jupiter copper foil coupling caps will help that amp.

@jasonbourne71 + 1 - good suggestions; many other NOS upgrade KT77s would sound better than Gold Lions as well. Tube upgrades can be very well worth it.  

1:NO YOU CAN NOT...
2:With your speakers why are you messing around with an amp other than the amps you know give you the sound you want?

@whyrichard Hello I went down a trail similar to yours, and so glad I left it all behind, what a relief. 
   I got involved with lots of tubes stuff my last big mistake was the PL EVO 400 pre, PL EVO 400 amp and just to put the big mistake cherry on top free falling down the rabbit hole the PL Dac. For a solid year I tried different tubes and spent a lot of money for nothing. When the amp blew a fuse and a EL34 stock tube quit working that was it for me, bought all new stock tubes and sold all the PL stuff to one great local guy. 
  Now what, no amp or preamp done with tubes I spent a lot of time with emails to Nelson Pass a great guy, (long story short get rid of  the tube stuff), I ended up with the Pass Labs preamp, Pass Labs XA-25 amp waiting for the First Watt Sit-4 to began production..the Sit-4 arrived 6 months later, it’s glorious, no more tube stuff running through my brain…do yourself a favor get solid state that sounds good to your ears, otherwise you will always be falling into that tube rabbit hole…I am now in music nirvana, Pass preamp, First Watt Sit-4 amp, Volti Audio Lucera speakers.

NEVER GOING BACK TO TUBE STUFF, MY WIFE BANNED ME FROM TUBES..
