I think it is a perfect combination. The quad widens the soundstage even more and every instrument has so much body, so much definition. Listening to just a hi-hat with this combination is already fascinating. I cant imagine a better set-up –unfortunately I have to let go of mine for financial...

If I were to change the tubes what about biasing? Is this a self biasing amp?

If you have a decent DAC already, I'd go for the Elise. It being hand-made in Europe is a big plus. And it comes with way better stock-tubes. @wangtox could you get yours to work now?

Is the static/scratching always the same? As weird as it sounds but mine is particularly loud when the volume is set to 0.

Welcome to the club wangtox! I suppose yours doesn't show the slightest sings of hum even with the stock-tubes? I am considering the Psvane CV181 TII (6SN7) but am unsure if they'd fit.

I couldn't agree more. It sounds so incredibly amazing on my HD800S.

@enduser would love to see a photo of the sophias in the amp as well : )

I just received a Quad PA-One + and listening to it currently. It does sound absolutely fabulous on my HD800S. I'm feeding it via USB. Wonderfully spacious, very detailed, overall super pleasing. There's one huge caveat though. It creates a hum in the left output when no music is playing. The...

Thank you! I’ll check those out!

Dear forum, after about 10 years my UM3 broke. I'm looking for a replacement now. I tried the TinHifi T1 and BLON unfortunately both didn't isolate well. On top of that the nozzle was way to wide for my ear-canal so it was painful wearing them for more than 10 minutes. I realised that I...

Anybody listened to the VA-One with headphones? How's the DAC?

Did anyone compare the Groove to the newer generation of Chi-Fi thumb-drive / dongle dacs? When I last listened to one about a year ago with a T90 it blew my mind. Now I own a HD800S and am looking for a DAC. Currently I feed it with an Apogee Duet but I wonder if the set-up can be improved...

The Momentum Wireless 3 are quite comfortable and have decent ANC as well. Haven't tried the Sony or Bose but compared them against B&W, Denon and Dali. The Sennheiser won when it came to sound and comfort.

I guess there's no alternative then…

I recently discovered the Nuraloop IEM. I really like that they are both wired and wireless plus they have ANC. Is there any other IEM that lets you easily go from a wired to a wireless connection. I know about MMCX bluetooth cables but I heard that the MMCX connector is prone to break. Since I...
