I think normal bias was 230V for Stax headphones and pro bias 580V.

I got exactly the same core cable made for the same reasons, Rob

The Phonitor XE is a low impedance output (0.36 ohms) - the original Phonitor 2730 had a 9 ohm output impedance and was too noisy with low impedance headphones, but absolutely loved high impedance headphones.

The original SPL Phonitor should work really well with the Sennheiser HD-820 too. It certainly did so with the 600 ohm Beyerdynamic T1 Gen. 2

I can understand this - in Australia, there seems to be a extraordinarily large number of companies going under at the moment. IMHO, COVID reduced their profitability to near or less than zero and the recovery hasn't seen enough financial stability to save them from debts incurred, which have...

Even Tyll Hertsens, who nobody has ever accused of being corrupt, didn't like to bag products he didn't like. IIRC, the AKG K812 (still one of my faves) was one such headphone and he resisted doing a review of it (and the Beyerdynamic T1 for the same reasons). Of course, if you won't review...

I also found Gradoist's review hard to reconcile with my experience of the K812. It isn't hard to drive and is *slightly* bright. The bottom end isn't accentuated - it's reasonably flat. Oracles1990 EQ brings in sub-bass and tames the slight brightness.

Nomax, is the new thing from AA you're talking about able to be used on already purchased Composer headphones (like new earpads or cables)?

Nice surprise from Amazon - a AUS$79.27 refund (??VAT refund as the new K812 phones came from the UK). Brought the price down to AUS$1463 (AUS$1000 less than the minimum Ebay price in Australia).

Arctic Cables Prisma I had them make up a Core basic cable (26ga OFC) with a Neutrik 6.35 mm gold plated plug. Very professional, fast and lots of options for colour, connectors etc etc.

LOL - to do this correctly, you'd need to completely disassemble your phones, buy a second left-sided cardanic structure and LEMO socket to modify the right sided headphone shell, rewire the whole thing with 2 left sided cardanic structures and the associated wiring into the LEMO sockets (ALA...

The Utopia isn't a magic wand! If the recording is bad, it will show it in the best light, however.

Let us know what you think.

Let us know what you think after an extended listen.

Have a listen to them with Oratory1990's EQ as well. That really whips an already wonderful sounding and well constructed headphone with some minor loose ends into shape! I just bought a new one too.

Fullbright wrote an Austrian/German headphone. OMG!!!

Let's hear his response then, because at a superficial level, his statement is incorrect.

IIRC, the Stax Lambda 4070 was a closed back electrostatic from last century.

In theory, yes. In practice, IMHO, no. Others will disagree.

...and getting them modified would possibly wreck the superb appearance of the phones. The K812 was apparently designed around running off the headphone output of a Macbook Pro. I've never used it that way. OMG @musicday , just buy a pair and listen to it as the manufacturer intended before you...

I've only tried the Arctic cable core and there was no difference in sound. The Arctic cable was more sensitive to what material it rubbed against compared with the OEM cable - so I went back to the OEM. It looks ordinary, but sounds good and handles well (minimal memory) compared with something...

Get yourself to a shop that sells the AKG K812/872 headphones. and listen for yourself, or get along to a headphone meet or show. Asking question after question without doing anything yourself won’t get you anywhere.

Just buy a K812 and see Amazon link to AKG K812 bargain.

I gave my son-in-law the old K812 and stand.
