LampizatOr Golden Atlantic + TRP

Can you provide a link to where you read that? I looked over the site again and didn’t see anything stating that. There is reference to “directly heated diodes” in the rectifier section of their manual. I’ve never seen a tube that has been called a “Directly Heated Pentode” as a pentode by definition has five elements- two of which are the filaments (heaters).

now that I read that URL, it seems to imply an older dac?

alot of old info floating around, the actual Lampizator site seems to have documents for TRP2

So I guess there directly heated pentodes out there but from what I’ve read they seem to be older, obscure and hard to find. There are a few articles on the web about guys who have built amps using these tubes but from what I’ve read it requires the ability to adjust voltages manually specific to the tube. I’d take this question to Lampizator as I don’t believe the newer TRP3 is setup to do this. Might be interesting to find out that it could!

I will jump in here and second the view on the SpaceTechLabs Super Tube Rectifiers. I use the STR 104 mk II on my Lampizator Poseidon DAC with great results. My experience has been that using the STR produces better sound than any single recti tube I have used in the Poseidon. I am currently combining a mesh type 80 rectifier tube with an 83 type mercury rectifier tube. I like to have one mercury rectifier tube in the mix because it gives a little extra body and umph to the sound while the 80 mesh tube adds finess, soundstage depth and detail, imho. Both are 5 volt filament so they can be mixed and matched (on the 120 volt version of the STR, anyway, but maybe not on the 240 volt version).

I liked the STR 104 mk II so much I decided to purchase SpaceTechLabs top preamp and amp, and another STR 1003 for the preamp. I’m glad I did because the sound I get now is the best I have ever had in my home, and perhaps the best I’ve heard anywhere. I am extremely happy with the SpaceTechLab products. I will post more about the SpaceTechLab preamp and amp in a future post in a different thread.

Thanks for sharing! I find the price of upper echelon rectifiers+adapters to be absurd, so this full wave rectifier approach is intriguing. What made you choose the STR 104 mk II over the other models? And do you find a pairing on non-mercury tubes (not gonna happen for me with kiddos...) to be significantly or marginally better then any favorite regular rectifiers straight into the DAC (sans STR104)? Thanks!

FYI I'm using the STR102super w/ 805 and 845 tubes. Turns the DAC into a way better DAC.

Thank you, the STR1002 looks intriguing, too. What made you choose this over the STR104? Big price jump here and more heat + more expensive tubes, but I'd personally absorb that for a big jump in sound quality. I don't suppose anyone has H2H compared them on their Lampi yet???

I chose the 104 mk2 model for my first order because I wasn’t too familiar with SpaceTechLab’s products and I wanted to start with a smaller investment. I was really happy with the result and so I subsequently have purchased their best amp, preamp, and the STR 1003, which I use on the preamp. I understand with children around that using mercury tubes probably doesn't make sense. You can use other tubes like the 3B22 tubes (with xenon gas instead of mercury) and still get excellent results. Or just combine regular 5 volt rectifier tubes, or use 300b or 2a3 tubes. Plenty of options. You do have to be very careful to set the filament voltage switch to the right setting, else you could blow your tube or blow up the transformer in the STR.

STR1002 felt like the right level of investment for me. Tubes are not uber-expensive unless you want them to be. Lots of options for tube rolling, but you don't have to mess with it too much. Glad I took the plunge -- no regrets.

Has anyone tried installing IsoAcoustic Gaia feet on their DAC? Do the stock feet screw off easily? If so, what size screw does it take?
