Answers to some FAQs:

Q. Can this play from USB or it Bluetooth only?
A. It's BT only.

Q. Can this charge and play at the same time?
A. Yes, it can.

Q. Is the battery replaceable?
A. Yes, the battery is socketed and can be swapped with an aftermarket one after unscrewing the unit.

Q. Where can I preorder this?
A. I got mine preordered locally from Awedyo Audio since they're the sole US distributor right now and next door to me.

Note — 8-19-22 — The following specs were adjusted to match the new specifications provided by Dethonray:
- THD: 0.01% -> 0.08%
- SNR: 110dB -> 108dB
- Single Ended Power: 1.2Vrms (32Ω) -> 2Vrms (32Ω)
- Balanced Power: 3Vrms (32Ω) -> 2Vrms (32Ω)
- Battery Life (3.5 Output): 10 hours -> 8 hours
- Battery: 2000mAH -> 3000mAH

The burgundy is such a nice colorway on this, hopefully it actually looks that good in real life.

Waiting for my sg1 now! Made a order 6 days ago!

Wow, just wow

Seems totally unbelievable. Design flaw or test setup flaw?

L7 does have a pretty solid reputation, so...

I know...Dethonray also have a solid reputation e.g. Honey...amazed that they apparently didn't test the device in a similar setup...L7 and Amir always do the same test sequence...

L7 updated the original post with a secondary measurement by a different person with a different AP audio analyzer and a different SG1, same result.

Talking to Awedyo Audio [where I got mine - he has a direct line to Anson], it's being looked into. Anson is currently working on a fix apparently and hopes to ship the fix soon.

Don't take this as a review, but I'm also, on initial impressions, hearing it to be quite weird and not what I expect from tracks that I know. I'm going to say that this SINAD deviation is likely the cause, but I don't have my own APx to test.

Shame on the appealing looks of the device! Seems that the device is basically a pass then.

Suppose it will either be discontinued or released in a Mk2 version quite soon...

Theoretically, Anson is suggesting that a software update is going to fix this. Will update as soon as i know more. Following up on this daily right now.

Note that the specs of the Pegasus have changed since its original pre-release specifications. Errata is in the top of the initial post. Pretty major changes to the THD and output power IMO.

The FIIO BTR7 has 150-200 times better THD+N numbers at ~50% of the price. The Aune BU2 (that I own) has approx. 550 times better THD+N numbers at ~87.5% of the price. Some other parameters are better on the Pegasus than on the other two devices.

How much is dapper looks worth?

In my humble opinion the only reason to buy the Pegasus is the looks. From a measurement performance perspective it is unfortunately a pass for me. We are talking about a device intended for “faithful reproduction” of music recordings after all. Waiting for the updated version.

Going to entirely agree with you here. Until I hear back from Anson, I'm a little hesistant about this device and can't really recommend it given the THD+N and overall SNR. I'm still waiting to hear back to see if this is entirely a software issue that can be rectified easily or a major hardware defect.

Dang, that measurement is ridiculous looking. Shame because I think the design is 10/10.
