I have an ENLEUM 23R and wonder how well it would drive the Immanis as a SS amp often stated to have tube-like qualities.

Be nice. I am an old man. Don’t read my posts if they irritate you. We are free to ask a barrage of questions to anyone who will respond IMHO.

How would you compare sound stage and the bass and sub bass between the Envy plus Immanis vs Envy plus Susvara? Also, did you compare the Envy performance to the Envy AE with both headphones above???

Direct plug and play for Immanis? Without need for transformer interface box?? Which would be a better pairing, HSA1b or Feliks Envy with interface box??

Will the HSA1B work with Immanis??

Cool. Just do it.

I think it would be nice to give a discount to SR1a customers or a trade in deal like Hifiman has offered in the past.

If the Arperio is so stellar and leagues above the other combos like Envy plus Susvara then why are they turning up on the used market for sale??

“Another absolute highligh was the Aperio, absolutely incredible system that outshined basically any other headphone on the fair that day for me. One day I want to preamp the thing with tubes or use a tube dac like lampi baltic with it. Aperio does everything Immanis and Susvara do but quite a...

The real question in my mind is whether the Immanis is so good Susvara owners would be willing to part with it. I loved the electrostatic detail, gigantic stage and speed of the SR1a but its anemic bass and sub bass was just too disappointing for more than occasional use not to mention the need...

Are there any comparative reviews between Susvara and Immanis? I was dissatisfied with the lack of bass and sub bass for the SR1a and although the out of head experience was unique, I always preferred the Susvara with smoothness and bass quantity and punch as well as sub bass that could be felt.

It comes with a cloth but to clean around the tube bases may be difficult. I would suggest building a custom clear plexiglass dust cover to be placed after the tubes cool off as a nice way to protect everything. The base would need four silicone bumpers or black felt strips along the base...

On the Envy AE, how would you compare the Susvara to Immanis?? Is the sound stage significantly more 3D (high/tall/wide) and pinpoint placement of voices and instruments as exacting as Susvara? What about bass and sub bass??

Please tell us how it sounds?? Any hum issues either external or with quiet passages. Is the background black? Sound stage?? With Susvara??

Disappointment is a somewhat scary thought, considering the significant upcharge for the enhancements touted by Feliks Audio. Somehow, I doubt that will be the case.

Anyone receive their Envy Anniversary Edition yet and have some comparison with the Envy performance edition?

Of the new production tubes, Linlai E-6SN7 Elite versus Psvane CV181-T-MII/2. How do they differ when paired with Elrogs??

Where do the Linlai E-6SN7 Elite tubes fit in here for new stock?

Best price and most reliable source for Brimar CV1988 6SN7???

Has anyone consider making a clear plexiglass cover box as to protect the tubes and as a dust deflector. It seems like it would be easy enough.

Any more impressions??

Is this tube the exact type used in the Envy Anniversary Edition and is this the best place to purchase from?? https://www.tubeampdoctor.com/en/psvane-cv181-t-mii/2/6sn7gt-matched-pair

This travel companion is amazing. Mint condition with all original items. Sadly had no time to listen and have to move on. “…but it is rumored there are only 60-70 SR1b left for sale……and I have not heard if there will be another production run. The SR is such a unique and capable ear speaker...
