Introducing the LampizatOr Poseidon DAC

[shadowlight]

I have previously enjoyed 01A in my Acuhorn on the 5v heater and they were stunning but the TJF PX4 mesh is even better. I imagine you can get a quad for around $1k USD.

I also found the 01A very microphonic given their age.

Can you share information on where to get the px4

Only one way to know how I'd think about the difference between the two and that's with both of them at home in my system for a while.

I’ve found Posseidon lean with stock tubes. With good nos tubes it is a totally different dac. Do you use F2a in your Atlantic dac?

Or you can do it like this )

But how do you "know" that a given heater setting is NOT frying your precious tubes over (maybe even) a short time?

Yes, good point.

To be clear, I'm not talking about running a tube that requires a low heater setting (101d, 45, 242, PX4, etc.) on a high heater setting (300b, T100, etc), for example. I'd never do something like that. The specific change here I'm referring to, is a minor one, in this case, moving from the 45 setting up one notch to the 242 setting on a Philips PT35.

Recall, some older model Lampi DAC's only had a toggle switch with two options: High heater or Low heater. So, back in the day, most tubes were not being run at the precise, optimal setting..

With our more recent Lampi's, we have options to fine tune. But yes, one has to consider the ramifications on tube life. I guess at some level, we are burning out our tubes every time we power them on. But, these Philips PT14 and PT35 are tough little buggers.

I received it with Siemens F2A and a WE 422a for my audition. Currently have Poseidon running stock input and output with a RCA rectifier (I'll try the Western Electric in it too)
