Not going to debate with you as you seem to have an agenda. I only shared what I've heard based on my own experience, which includes ownership of the Oor/Hypsos.

No issue with you (or anyone) preferring the Utopia, but if you only tried the Susvara on a Ferrum Oor (and especially if you didn't use the Hypsos), then I can say from my own experience that you likely didn't get anywhere *near* the Susvara's potential. FWIW the Susvara can throw a massive...

Can you explain what you mean by “improvement on sound”? Is it better or just different? I’ve always used the stock pads but would deffo give pad rolling a shot if it brought noticeable improvements to the aspects of SQ that I value.

The HEKse is a fantastic headphone. Don't be too quick to "upgrade" to the Susvara. In my own experience, moving from HEKse to Susvara was initially a step backwards in several areas of SQ, including bass, impact and slam, soundstage width and height, treble sparkle and frankly, overall wow...

Good info. If I strike it rich someday, I'd love to try the Inpol2 Mk II (https://upscaleaudio.com/products/pathos-inpol2-mkii?variant=41056160121016). Dual mono, pure class A, 2 x 45W @ 8ohm. *drool*

So just a random data point on an amp I've never seen mentioned here: Pathos Acoustics ‘Classic Remix’ integrated (https://pathosacoustics.it/en/non-inpol-amplifiers/classic-remix/). This is a fully-balanced hybrid design with 2 x 6922 tubes for the preamp section, and a class AB SS power stage...

Excellent buyer. Fast payment and great communication. Very smooth transaction. Thanks!!

Looking for a speaker amp adapter cable. Prefer banana plugs but would consider spades, as well. Thanks!

Yes, the stock FPL cable (pictured) is included. Thanks.

Just in case anyone is looking for a Ferrum stack, I've just listed mine for sale here: https://www.head-fi.org/classifieds/ferrum-oor-hypos-stack.30530/. PM me with any questions. Thanks.

FS: Ferrum OOR Headphone Amplifier with Hypsos Power Supply. Like new condition; purchased only 4 months ago and used sparingly. Original owner. Includes factory triple boxes and all original accessories, paperwork and packaging. Asking $2450 plus shipping and PP fees if applicable. This is...

agreed. as i've said before, the ferrum stack requires some care and feeding. the hypsos is a great power supply, but sound quality (especially soundstage, depth and detail) improves *a lot* when you feed it from a good line conditioner. cables make a difference, too. fwiw i use medium gain...

Smooth and easy transaction. Fast payment, no hassles. Thanks!

what does the sensing feature do? do you also disable spread spectrum? what voltage are you using?

FS: AudioQuest Mackenzie RCA to RCA Interconnects, 0.5m. Purchased 3 months ago from authorized dealer. Like new, with original box and packing. Excellent sound quality. Retails for $270. Asking $120 shipped including PP fees.

amps that produce a wide soundstage (e.g. soloist GT) often sacrifice depth, imaging and/or tonality. always tradeoffs. to me, ferrum strikes the best balance of all the amps i've tried. non-fatiguing, pinpoint imaging, and a very deep soundstage with reasonable width. it did require some...

Has anyone compared the iFi iPower Elite against the Sbooster BOTW (with or without Ultra upgrade)? Thx.

im using a chord qutest and the pairing is excellent imo. single ended only, however, if that matters to you.

I believe the ferrum stack takes some care and feeding to sound its best, more so than other amps. not sure if you're a cable believer or one of those ASR climate denier types, but in my chain, which is similar to what you had (qutest>ferrum>susvara), upgrading rca interconnects made a *massive*...

the ican pro signature sounds nothing like the oor/hypsos. owned both, kept the ferrum.

whatever dude. good luck.

in my experience, the soundstage you get with the susvara is massively dependent on your electronics and really, everything upstream, including cables. have you experimented? you can get a huge soundstage with the stock pads.

has anyone encountered a big change in the oor/hypsos after break in? after ~100 hours of pink noise, the SQ improved pretty dramatically for me. wider and deeper sound stage, better layering and more bass impact. coming from the soloist GT and ican pro signature, id say the oor/hypsos now has a...

yeah that's probably the case and not a big deal. however, even minor differences could make the discussion about revisions more complicated, e.g. do we need to distinguish 4.2 (axiom) from 4.2 (nexum)?
