That's a nice looking PSVANE KT88 there :)

You will need a preamp or digital volume control to the Vali on Campfire IEMs because the volume play is almost non-existent! Let me know how it goes!

No EQ for me. I think your DAP/source is emphasizing the treble note edges too much if it's peaky/aggressive, and EQ IMHO will sacrifice finest refinements in the note edges. I even use the Pentaconn Corier Brass to make the treble (and the whole frequency range especially the bass) even more...

Got my 119dB SINAD Schiit R2R DAC for that no coloration signal :sweat_smile:

Aegis 2x 6SL7, 2x pentodes, 5V/2A rectifier tube

It’s very common in Asia to use such clever poetry to showcase their products. I personally like the way they put mysterious descriptors to their products :)

At max volume, Susvara is enough to go listen to almost as loud as IMAX movie theater levels when watching Netflix movies, but even at max volume, Aegis and Susvara won't make you uncomfortable even at that level of loudness due to how very refined sounding both of them are

This is assuming every part of the DAC is working in perfect ideal conditions. Doesn't take into account the clock jitter, noise floor modulation, digital filter mathematical interpolation or lack of thereof and circuit design and implementation in analog and digital section of the DAC, let...

With the DCA Club discount, I'd put it on the at least top 2 or 3 of the best closed back headphones on its price range. I need to hear the Liric 2 first but E3 at 1.6K for a closed back is really amazing. Makes Hifiman Audirvina sound like a kid's toy headphone

Same with the even cheaper TAD KT66 (also Chinese made tubes IIRC) though some Aegis users find it not so good on their system

Aegis is a special amp no way one would let go easily. I'm forever very pleased to be the recipient of his first build :)

You should try the DCA E3 and get even bigger soundstage which to me is either equal or slightly larger than the DCA Stealth :)

Don't forget to buy 4x AHB2 and run them as Bridged Mono to the Sus :wink:

You don't really have to spend that much for a entry Susvara amp heck some people are happy with their Topping A70 Pro driving the Susvara. Until those people get a really good grasp of how good Susvara sounds when it's on a really good chain, ignorance is a bliss

On A NOS and filterless DAC, that would show up exactly like that (tons of images). With proper filtering and reconstruction though the 12KHz square would show up as 12KHz sine on the scope as confirmed by @Quazar
