Shiit vali 3 is certainly a great playing hybrid with a tube as a preamplifier and the output stage is solid state. For the HD660S2, however, an OTL amplifier is more recommended, and I myself am very satisfied with the all-tube amplifier xDuoo TA-26 and even better the Eufonika H5M (but this is...

Sorry for the trouble with google translate on my smartphone...

Well, the fact is that the symmetrical cable that I ordered from Hart Audio Cables, or rather the locking connector, is very hard to insert into the NDH30 and even harder to pull out, compared to the original Neumann cable. Maybe the diameter of the connector body is the problem. Hart Audio...

No je fakt, že symetrický kabel, který jsem si objednal u Hart Audio Cables, respektive ten zamykací konektor, se do NDH30 velmi špatně zasouvá a ještě hůře vytahuje, oproti originálnímu kabelu Neumann. Možná je problém v průměru těla konektoru. Hart Audio Cables mají zřejmě jeden typ...

Thank you for the information, I'm in no rush for the cable, so with your permission I'll wait until you try your cable from LunaShop. ;-) I can initially use the included unbalanced cable in the xDuoo TA-10R desktop amplifier, but I also want to listen outside the home and for that I need a...

Thank you for your message! ;-) I was surprised that the Ali seller LunaShop didn't have any balanced cable for the NDH30 in the offer, so I had to order it to order from the US from Hart Audio Cables and it wasn't cheap with shipping and customs. The verified LunaShop offers braided...

Well, I'll wait until the headphones are home sometime and try a balanced cable for the NDH30. I'm still waiting to hear from ericpalonen and then I can still order a balanced cable from Aliexpress, I already have several cables from LunaShop for all my HD6** series headphones and I'm happy...

Hello, I have been watching the new HD620S headphones since the first mention on the Internet and I am excited! Among other things, I have Neumann NDH30 headphones, for which I purchased a balanced cable from Hart Audio Cable terminated with a balanced 2.5mm TRRS connector to connect to the...

It's a little off topic about the 660S2, but for me the KOSS PortaPros got a second chance for listening outside the home after discovering and trying the Morphit plug-in in the USB Audio Player Pro. After searching for KPP in the list of headphones and setting the target curve, the Studio...

Congratulations on a beautiful yet brutal amplifier!!! Could I ask about some available parameters (power) and what tubes are used? ;-)

I also wish everyone a happy new yEAR! (this is what Wieslaw wishes...!) ;-) I didn't like the upward headphone output and it seemed prone to damage to the cable at the connector. The idea with the input sensitivity switch occurred to me already with the TA-26. Because I have a DAC with a fixed...

I had the amplifier made by Wieslaw according to my ideas and he made the amplifier perfectly as I wanted. My requirements were: a transformer admitted outside (I'm "old school" and the transformer simply belongs to the tubes + better cooling of the transformer), headphone output connector from...

So the Christmas gift for me manifested itself in the form of a headphone amplifier and I am a new user of Wieslaw's work and that is the H5 KPCU, which was created exactly according to my ideas... I am delighted with the sound and my HD660S2 sounded better than with the TA-26. Just a small...

The HD600s are back from repair and playing great again with no rattles. Changing the springs helped...! ;-)
