Yeah, that might be accurate. I've updated my earlier post with a link to someone's testing of AirPlay throughput through different combinations.

Unfortunately, no. Apple seems to have prioritized streaming to multiple endpoints at lossy rates rather than lossless streaming to a single endpoint from iOS. However, it appears to be possible to stream at 16/44.1 via AirPlay from a Mac but only if the endpoint is selected in the System...

Just now experiencing a tube hp amp for the first time with Aeolus and…wow. The difference is stunning. I liked these headphones before but now I can’t put them down.

Focal Clear. Well cared for and in very good condition. These open back headphones are very well reviewed and highly popular for their clean, full, neutral tuning and excellent detail retrieval. I've enjoyed these but haven't used them much since turning toward ZMFs, so it is time to move them...

Very reasonable price, good communication, prompt shipping. Excellent experience from start to finish.

I appreciate the ethos that you've established of quality craftmanship, unique designs, and superb, direct service. Bokeh punches well above its weight within the current headphone market, and while it is still a lot of money for most folks, the experience and the object are entirely different...

The Topping a90d provides more than enough voltage for high impedance HPs to reach unlistenable volume levels without distortion setting in. https://www.audiosciencereview.com/forum/index.php?threads/topping-a90-discrete-review-headphone-amp-preamp.35114/

It appears that the damping factor of the amp that you recommend is actually quite high (listed as 100 balanced, 200 unbalanced in the documentation) since the output impedance is very low: .5 ohm balanced, .25 unbalanced. So that amp is quite transparent and shouldn't be changing the FR due to...

Interesting, thanks. The spec/promo sheet describes it as having "the lowest output impedance" and indicates output impedance at .5 ohms, so I'm not sure if it is high impedance that distinguishes this amp. Maybe it's the "damping factor?"

Can you say more about an amp's "voltage swing" capability and how that is measured? My understanding is that high output impedence of an amp can restrict its capacity to drive high impedance headphones, but maybe I've misunderstood. I'm getting this here...

Looking for (more) pad advice. Can anyone say how Ori Suede would differ from Universe Suede? My impression is that both are on the bassy, warm end of things but that the Universe have a larger ear opening and might create a bigger sense of space. Is that about right? Any other impressions about...

Prompt payment, good communication, smooth transaction.
