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!

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?
