Primaluna DiaLogue Premium preamp


Hello all.

I just wanted to drop a quick note to the forums stating that I purchased a Primaluna DiaLogue Premium preamplifier about a month ago from Upscale Audio.. (thanks Kevin for your help).. and wanted to convey in some way how pleased I am with my purchase. I was using a solid state unit for a lot of years [at nearly three times the cost] and as much as I enjoyed that unit, the Primaluna is in another league compared to quality of sound,which of course, would be the reason why any of us look to upgrade our systems.

This preamp has a fantastic way of causing the natural sound of the music to ebb and flow that only a well made tube pre can do. As expected, the mid's on this unit are glorious and just plain sound like real music, communicating to my ears what tubes do so well,that is...a naturally organic and live..be there.. musical presentation.

Also,as much as the mid's impress, the highs and lows are just as good as the mid's. The bass on this pre just plain rocks. This thing digs deep and does so without any reservation. I never would have thought that a tube preamp could have better bass performance than my solid state unit..but for me,in my system, without a doubt, it most certainly does. I'm guessing the high build quality and the massive transformers used in this design are the reasons why it digs so deep, and does so without apologies.

The highs are yet another fantastic area where the Primaluna grabs your attention, and I mean so in a most positive way.The highs are very natural and revealing at the same time, without any added fatigue or brightness in presentation.That in and of itself is a rare combo for any piece of kit...let alone one that is so reasonably priced,that is.. by high end standards.

The reviews of this preamp online by some of the better rags out there are a fair and truthful assessment of the virtues of this preamp. I can also give the Primaluna my highest recommendation to anyone looking for a musical component that really does deliver the goods in a smart and beautiful package.

I would like to thank Primaluna for a great job in the design, build, and sound quality of this DiaLogue Premium Preamplifier. And to do so at a fair asking price is the icing on the cake.....

Kudos Primaluna!!

Why do they use those 5ar4 tubes? I look at the CJ ET3SE and VTL 2.5i and ARC preamps and they don't use them. Why not?

I just looked up Cary and they don't either except on the SLP-05 but that's like $9k or something.

Sorry to be a pain.
Well I finally pulled the trigger and bought a PrimaLuna Dialogue Premium preamp and matching HP power amp. I would have been happy with the integrated but I wanted to get something that I would not have to replace ever and I contacted many owners here privately to see if they are happy after the newness where's off. I may end up getting some Magicos or Wilsons later and being able to mono bloc the amps, as well at being able to run KT150's seemed to be a good idea.

As to the preamp: I spent a lot of time with different preamps. What's important to me is a natural organic midrange. I use high Rez downloads but have also started streaming using the higher quality Pandora and more recently Tidal. We're it not for tubes streaming would not be listenable. If anyone out there streams I would encourage having a a tube preamp as a minimum and better yet also an amp.

I tried an ARC LS17SE. It was just a no go. I felt it held things back. So I went to the LS27. Now we're talking. Better in every way in comparison, BUT I then tried a Cary SLP05 and the mids were fuller. The LS27 uses the 6h30 tube so there was no way to use a different brand of tube to get the midrange liquidity I wanted. The Cary has 6SN7's and you CAN roll them, but they are expensive and it seemed like using different types may not be great. But still the Cary was my fav.

I also tried a VTL 2.5i. It was less money than the Cary, and uses 12AU7 tubes which is where I wanted to be for tube rolling. I liked it OK.

I also looked into the Conrad Johnson but after seeing the complaints from owners about noise and microphony problems I passed.

So now I was pretty satisfied and looked into the PrimaLuna. The Cary has a 5AR4 rectifier tube in it, and I feel that had an influence on the liquidity in the mids. But I did a side by side with the Primaluna (doing ANY side by side was almost impossible) and BANG there it was. The liquidity I wanted, but more important the noise floor dropped. I didn't realize that there was any noise before until I heard it removed. That's something I have to stress. There is, with many preamps, a very low level hash not even perceptible if you look for it. The only way you know it's there is to have it gone.

The Primaluna uses 12au7 tubes and that's great. I've looked and there are so many types of new old stock its dizzying . The build is impeccable. From another planet compared to the VTL and lower priced ARC.

The store I bought it from put the full court press on me to buy the ARC. They pushed. But after I bought the Primaluna from them the store owner said something funny "I wished they charged more for it". I stinks that they were motivated by higher dollars so much.

But I also wanted a matching amp that is world class and not a hassle to own. Even he admitted Audio Research amps require more hand holding that I'm not willing to do.

If anyone has suggestions about tubes and the Primaluna I would like to hear about it if you can post please. I don't feel a single urge to change a thing but people tell me it's a lot of fun.
Thanks. I'm buying speakers and will most likely do tubes to fine tune. I called Upscale and Kevin was terrific and though people came up to him saying someone else was calling for him he said he's call them back and stayed with me to talk about not where I'm at now but where I'm trying to go and that was refreshing. Dealers don't do that. They just blurt out "this is the best" without asking anything about me.

He has some 7316's he said but would have to find them and if I want some he would try. He said that they are the same thing as an Amperex 12AU7 but they were designed for early computer use and read some stuff from an Amperex book. At that point it was over my head.

He said that I could use most any tubes I want. But the speakers I'm looking at are slightly demanding so he mentioned KT150. I'm going to investigate.

I am extremely happy with my choice in PrimaLuna. I like fine mechanical things like cars and watches.

I'm trying to think about how I would compare PrimaLuna. Maybe like a BMW M3. Incredibly fast and as quick as Italian exotics on a track but not priced like one. And you can drive it every day. Had I spent more it would have been for ego.
I asked that question before I bought my PrimaLuna. The top of the line preamps from Audio Research, BAT, and a number of others use tube rectification or regulation, and so my assumption would be it is better if it is possible $$$ wise.

I had looked at the Cary SLP05 preamp, and it uses a single 5AR4 rectifier tube. The PrimaLuna uses one for each channel.

I have to say I took mine off the rack and removed the bottom panel and it is incredible. I am amazed by the insides and even the finish of the chassis. It's a rich gloss paint. Very nice and a far cry from flat black that others use.

I am also thinking about changing the rectifiers. I got the message from Kevin that using the Philips 5R4GYS isn't automatically an upgrade. It is warmer. The preamp is so perfect stock I don't know if I want to take a chance. I suppose I could keep them for a rainy day.
