Not released yet.
I have a little info on it as I've been in touch with Anson lately about my (ex-)Honey.
Basically, it will it be less powerful than the Honey but still powerful enough to easily drive the HD600/650. It will be BT amp only - no USB DAC. Early bird offers will start in June - so I guess it's finger on the trigger time for some.
I love the look of the SG1 and the fact that it has built in playback controls.
But I used my Honey with Arya V2 (among other greedy cans) so power is essential for me as is USBDAC functionality. I'll probably (enviously) pass on the Pegasus and either try and pick up a replacement Honey or sit tight to see if Dethonray release a new USB DAC soon.
Separately the Earmen Angel looks interesting but I imagine it won't have the lush Dethonray sound signature, and will likely sound comparatively analytical/sterile (not a criticism - I have other DAC/Amps that do that for me already - monolith thx portable, topping NX7, if micro idsd signature.... But I miss my Honey).
For anyone wanting to offer condolences, basically my Honey USBC port broke and it was out of warranty. Anson kindly offered to fix it, but frickin' Royal Mail lost my device before it had even left the UK and I'm not able to claim anywhere near the value lost
.
With that in mind, if anyone has a Honey in good condition they'd be interested in parting with and can ship to the UK, let me know. I may be tempted.
