    Tube pre amplifiers

    Hi Actually, I have a whole collection of "Holy Grail' 6SN7 types including the venerable TS round plates, the Sylvania bad boys, national union, ken rad, and many I have forgotten. I sold most of them off because to my ear the Linlai E-6SN7 and the Shuguang WE6SN7plus (which is FINALLY back in...

    Tube pre amplifiers

    Hi I knew when I posted that I would get in trouble:) I am looking at that pre online. I see banks of lytics and small signal tubes and coupling caps. Based on decades of experience I don't have to listen to that preamp to know what that sounds like, no matter how well you build it. It...

    Tube pre amplifiers

    In my experience rebuilding hundreds of pieces of vintage tube gear, including some of the top tube preamps of the day, building hundreds of my own preamps for sale, and now producing my final design as I at least semi-retire, small signal tubes should be avoided. The larger the plate, the more...

    thanks. I will have to write the mods to figure out how to be changed from Member to Industry Expert. Are any of us really experts?:)

    Tube pre amplifiers

    OK, I don't want to get in trouble, so I will state right up front that Lynn Olson and I designed a sort of cost no object set of 300b push pull monos (prototype in my signature block there) AND a matching preamp. They are now being made by Spatial Audio Lab in Utah. The preamp is pretty much...

    Lampizator Valve / Tube Rolling Review Thread

    Hi Dual ring getter at base. They are definitely rings, not dish, and there are two. Single mica. Here is a photo from the seller's listing

    Lampizator Valve / Tube Rolling Review Thread

    Much better than the RCA and GE 5R4GY I also have. At this point it is probably better than my Linlai WE274b, which to date is the best rectifier I have heard in my Pacific. The Brimar is good enough that it can stay in there for 100 hours to run in. I kept swapping the RCA and GE out and...

    Lampizator Valve / Tube Rolling Review Thread

    One more vote for the Brimar 5R4GY. Picked up a British made NOS one and it surpasses anything I have tried in my recently updated Pacific 2. Excellent tube.

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    The Brimar 5R4GY arrived today. Indeed it is NOS and British made. Works perfectly. Been on for 30 minutes and is astonishingly good. Much better than the RCA and GE 5R4GY I also have. At this point it is probably better than my Linlai WE274b, which to date is the best rectifier I have...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Based on the really long Lampi tube rolling thread, which has a pretty low signal to noise ratio:), I found a good deal on a Brimar 5R4GY, so will try that. My old GE 5R4 sounds good, but I prefer the top end sparkle of the Linlai 274B. Will try a fine British 5R4 and see. Also have to roll...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    OK, now it has had plenty of time on it. As others have stated, it is hard to imagine this was the same DAC. It is levels above what it was! I tried some Gold Lion 300b I have as backups for my amps and they were OK. The original RCA NOS 45 I have sound thin and bright. The Sophia 45 mesh...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Yes, currently running a quad of Sophia mesh 45 tubes, and a Linlai WE274B rectifier. Sounds pretty darn nice.....

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Finally got my Pacific back through customs from Poland after the upgrade. Yes, the upgrade is a no brainer. Better in every regard. Better separation spatially of all elements in the sound stage, and hard to believe, but better tonality and realism of everything. Subtle decay of things, the...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    OK, I finally sent my Pacific in for the Pacific-2 upgrade. It is on the way to Poland. I will report back in a couple of weeks when it is safely home and playing music. Right now I am using my old Schiit Yggy just to create some music. It is sadly lacking compared to my Pacific..... sigh...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    So the difference between the Big 7, GG, and Pacific was the addition of active anode loading in the Pacific. The Horizon has a whole new digital engine of course, but it has anode loading and some sort of cathode loading as well using the pentodes and the 6SN7 is the actual output tube instead...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Thanks Golum. I was searching for variations on Pacific vs Horizon and not just Horizon. I found it. There are many responses, but I found the one by Lukasz stating that the KT88 and such are anode loads, and also cathode and the 6SN7 and such are the actual output tube. Fine, that tells me...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Thanks so much for your reply! That is exactly what I was after. Someone who actually has lived with both. Of course economics are an issue, but I may be demoing some gear in Seattle at the show, and I think I can wrangle a Horizon DAC loan as the source. Not sure it will all come together...

    Anyone have impressions of Lampizator Horizon vs. Pacific ?

    Hi all, I have had the pleasure of listening to a Lampizator Pacific fully balanced for quite some time now. I am using type 46 tubes with adapters as the output tubes. Honestly, I have never heard anything that can touch it, but I have not heard all the SOTA DACs discussed in this forum. I...
