I am looking through the thread for tubes to try. Could let me know what tubes are this? Are they 6N1P-E?

Which tubes?If anyone wants to experiment with tubes in the Posseidon or Pacific we discovered a new 6N1P substitution tube. Game changerUltra linear, ultra low noise and so much fun to listen.
I haven't rolled tubes. I've lived with my Poseidon for 8 or 9 months. You should listen to it for a while prior to changing tubes. It is a great sounding DAC and pre-amp with OEM tubes. I don't have a SOTA system but it's high end.

I recently heard my Poseidon with Bendix 5992 tubes with a Mullard GZ34 fat base rectifyer and the combination was easily the best I'd heard. The Bendix tubes took some of the harshness in the upper trebble off the GEC 6J5 tubes I've been using whilst maintaining the leading edge dynamics and overall musical coherence, whilst the Mullard recitfyer added a lot of useful separation and imaging to the sound.
Sadly, it seems that Bendix 5992s are something of a holy Grail tube.

I have a bunch of Bendix tubes which are unobtainium if anyone is interested. They are mint

so Ive been corrected...my Bendix 6900 are signal and not output tubes . Having said that when the H1 was released it was Lukasz favorite
Lampizator announcement: launch of our all new TOTL HORIZON DAC
Probably the least important thing to consider when auditioning new gear. As it was phrased so well in the movie Beauty and the Beast as well as Lukasz in an earlier post above ....."Beauty comes from within" Maybe that's why I listen with lights out so that I am not distracted by looking at the...

In my Neptune (which is same tube types as Poseidon), I am using JJ 6V6S instead of 6J5 and it is exactly removing the harshness. JJs are new production, inexpensive and excellent sounding.
6N6P have been replaced by E288CC (no adapter needed) with great results as well.
I am also tempted to try new production 6N30P from EH or Sovtek. Has anyone tried these already?

Anyone try EL34/6CA7/KT88/TK77/6550 type of tubes in place of 6V6, provided that they are supported?
What harshness are you speaking of? I don't hear harshness in my system.
I read this on-line about using E288CC tubes instead of 6DJ8/6222/E88CC tubes.
"The E288CC / 8223 are absolute top sounding special quality tubes. They are not exactly the same as the E88CC / 6922. They require a little more heater current (0.475A against 0.3A) which the amps power supply has to deliver.
Also they have slightly different amplification and plate impedance, but this is not problem in common E88CC circuits."
Regarding the harshness, I was referring to stock 6J5 which are good but a bit "crude" sounding tubes. When replaced by 6V6S from JJ Neptune gets even more natural timbre and a bit bigger soundstage.
I am very happy with E288CC replacing stock 6N6P in Neptune. E288CC is also a very significant improvement in my Pacific - truly great.
On Neptune page in Lampizator site it says:
Tube compliment:
1 x 5U4G rectifier or equivalent, 274B, 5Y3, 5C3S, GZ34, GZ37, GZ480, 5AR4WGB
4 x 6N6P dual triode as input buffer or adapter fitted 6900, 12BH7, 7119, ECC182
4 x 6J5 or KR5 or 6C2C single triode as output buffer or 6V6 pentode (without adapter) or EL34, KT66, (or 6888 with an adapter)
I have tried some basic EL34 but they were not better than stock 6J5. In my setup much better results are achieved with RCA 6Y6G tubes (not expensive and no need for adapter, confirmed by Lampizator team that they can be used). JJ 6V6S are still better than RCA 6Y6G though.
