Hi, can someone point out the differences between Iris and Iris 12th, please?

Agreed, that's why I asked it in multiple different ways in order to minimize the chance of a hallucination and the numbers provided were consistent. Schiit does not provide these specs to my knowledge, so unless I e-mail them there is no easy way (or at all) of finding out.

Schiit just replied to me that they did not recommend using any tubes besides 6N3P, 2C51, 5670, or 396A.

Thanks. Schiit's LLM bot replied: "Vali 2++ was designed to work specifically with tubes that have a 2C51 pinout, 6V heater, and less than 600mA of heater current." Unless these specs are incorrect, it looks like it will work.

Can someone verify whether Vali 2++ is fully electrically compatible with 6SN7 and 6922 tubes using a simple socket adapter (i.e., besides the "trying it, working fine and has not blown up so far" type of testing)? Many thanks

Insane cost…

George Chronis will be able to advise on that when he receives them. Ask him.

I'd be interested on this comparison too. The Z1R do not produce an entirely mainstream sound and they are rather peculiar in terms of DAC-Amp matching. As a result, reviews have been polarising, ranging from "the best closed-back headphone we've heard" by What-HiFi to the veritable...

Does anyone know what size is the Monoprice Cavalli Liquid Platinum amp's power adapter tip? Is it 5.5 X 2.1mm, 5.5 X 2.5mm, other? Thanks

Try one of the Amazon sites… I think they’re available in the US or Australian one… see if they ship to you. Also try Hifishark: https://www.hifishark.com/search?q=Pioneer+se-master1

Your inability to read and comprehend English seems to be second only to your behaving like a brat.

You're welcome.

I already answered, you just chose to focus on a non-salient part of my reply. :)
