Pacific dac: Lampizator's new top of the line dac

[christoph]

Has anyone tried a solid state rectifier?

For burn-in of the PAC itself
Doesn't really sound good at all

Sounds like something a proctologist might prescribe

Not pleasurable

In my system, they are exceptionally transparent and holographic. They reveal much more information on the recording- a resolution enhancer, with no weakness in the frequency spectrum. Like going to a super high resolution television. But the key is, this tube is definitely not sterile, clinical or bright. They present with a very natural and realistic sound. A hard combo to achieve in my experience.

The improvements are relatively shocking. Not subtle.

One word of caution, if you are looking to increase the existing level of warmth in your system or push your sound to a warmer, fuller, rounder presentation, these are not going to do it for you. They are neutral.

Of course, others may hear them differently.

EDIT: On another note, I also have the Fivre 5Z3 rectifier posted above. It is a really nice tube and adds some additional body, heft, fullness to the sound, without rolling things off, a good combo with the PT14 and a great all-rounder for a rectifier.

@Blake I have a quad of PT14 ordered. My question is about how long a burn-in period?
Currently i have ShuGuang 300Bs. Thanks

I was hearing something special cold out of the box, even without burn in, but if you like them after 50-100 hours, then they are keepers. They continue to improve after that for perhaps 300 hours or thereabouts.

I find the PT14 have a certain softness despite their great transparency.

Is anyone else hearing that as well or are my exact tubes just too new and the softness will diminish with more hours of use?

Tubes usually get "softer" as they break in. I have not yet encountered the opposite...until they are about to fail perhaps.

I think I now understand…

That is my experience as well.

Stupid question
Is U52 tube fitting Pacific?. Seems like that tubes have bigger diameter (base) than regular ones?
Cheers

 

[Sablon Audio]

Yes, U52 is interchangeable with 5u4g

Thanks, I wonder if the diameter of the hole in Pacific will be enough to fit U52 that has bigger base?

I would say no. I had a same issue so a friend of mine helped me with producing a new top cover for Pac with wider & perfectly centered holes for the rectifier and DHT tubes (i could plug T100 without adapter).

Thanks Golum, I thought so looking at tube socket …

Wait until you get rid of the 6N6Ps

My brown base GEC U52 absolutely directly fits with about 1-2 mm radial clearance.
I’d imagine if there’s variability and issues then a “tube socket saver” spacer would make it fit.

What is your favorite for that position?

 

[Anyoldears]

What is your favorite for that position?

Personally trying out Tunsram e83f and previously had Tungsol 5687 and Sylavania 7AF7. Not much in them all, all are good, maybe the Tungsram e83f is currently leading. Hoping to get a TP adapter for them soon to see if that changes things....

These are in the Pacific

Do all of these tubes need (different?) adapters for the 6N6P position?
