Do you have any of the other Sennheisers /similar level closed backs to which to compare? As you say, though another closed back, Liric 2 is a $2k USD headphone, it ought to be much better technically.

Will be interested to hear your detailed impressions after burn-in. @ericpalonen, how long is burn-in recommended for the 620s?

Have read through the thread till now and will finally weigh in here. First, @Sennheiser friends- I predict that this is going to be a very successful product indeed. It may have a more mainstream than typical audiophile “reference” appeal, but there are plenty of us bass-heads (in the most...

Jim and Charles at VnM are great people. You will not regret your choice I think. I have their Canadian Gold Freya+ set which is 2 GE GTA NOS and 2 Marconi GTB NOS- great air on top, smooth mids, punchy but textured low-end. Not the cheapest but the quality and service is good. Pls they have...

See earlier posts this thread on ‘protection circuit’. You must not play music from C9 while C9 and the DAC feeding C9 are powered by the same power source eg a common power block, as there is a common ground between the audio and charging circuits. It will create a short circuit and may damage...

I will just say this “Susvaras though…” They may be outside your budget (though nowadays one can get a pair for about 50% of MSRP). Some critique build quality even at that level. For me they have been perfect even so and a revelation. One must be willing to drive them properly (there is a...

All I use as well and ever will: 1) they work great and 2) once I start down the path of inter-connect comparisons I know I’d never stop. It’s a game for those pursuing the very last iota of SQ excellence. I’m working on my ‘JOMO’ these days.

Have had mine for 2 years without anything falling apart; HOWEVER, one time I had them on the plane and one of the stock tips (not flanged) which I love and are so easy on the ear canals fell down between the seat bracket and the sub-flooring to which the seat was attached. I had to nearly stand...

If it has been only warmed up a few hours and it’s been off for a long time before that, you might better let it settle for a few days then re-try your test. Whenever I go away and leave Yggy+ OG powered down, it takes 2-4 days to get back to its full OG self. A few hours is likely insufficient.

I too - Isotek Evo3 Premier right from the start https://www.crutchfield.com/p_191E3PRM15/IsoTek-EVO3-Premier-C13-C15.html?omnews=17919655

Sorry to hear this. I have been running an OG without hum for over a year. Ground loop can be an issue to resolve, but it sounds like you have already moved on- hope you are happy with BF 2/64.

Ditto to all good OG comments. I’m having JOMO on MIB at the moment (excellent as I’m sure it is though I take SBAF and @theveterans word for it) as I just added a Freya+ to the mix with upgraded NOS tubes (GE GTAs in CF, Marconi GTBs on gain). It’s like dialing up the slam on bass without loss...

New Freya+ on deck- VlavesnMore NOS 6SN7 GE GTAs on cathode follower, Marconi GTBs on gain. Right out of the box impressive (but this is my first serious tube pre so comparing here to a SS DAC amp system I dithered a long time wondering about pre-amps, but in the end stayed with the original...

Do let us know how Schiit handles this for you. It sounds like you have a defective GS2, which is a shame but happens. I’ve had no such issues after a year of use with an Yggy+ OG, I too have a not so clean power context, this sounds like a unit issue.

I have never had a problem with this. I have XLR out from Yggy+ A2/OG to a Burson 3XGT and SE out a Douk pre-amp which then goes SE out, also into the 3XGT. I have changed Yggy+ outputs with both the direct-to-3XGT and pre-amp connections all ‘live’ with no problem whatsoever. I never had an A1...
