I am currently auditioning this very animal using my HiFiMan He500, I am thinking REFERENCE level amplification…………
This is the builder Justin Weber’s variant on the Darling circuit using the 1626 tube at 3/4wpc it is driving my phones easily as good as my 3wpc EL84 tube amp.
The amp is the most revealing I have heard, all the nuance in vocals shines through with ease, I have always associated SET with romantic / warm / syrup…………….Not the case here with ZERO feedback this thing is as crisp and neutral as one would typically associate with High End solid state……………..but with absolutely no hint of grain or edge. And DEAD QUIET to boot, Music just emanates from a solid black background ( it’s almost eerie, yet welcome).
Bass is tight, deep, and controlled. tones show rumble at 20 hz on my cans, while I can hear tones as high as 15khz.
Bela Fleck, Flight of the Cosmic Hippo, bass is surprisingly guttural at 3/4 WPC This thing is amazing.
Sometimes God Smiles, track 20. Prism is a drum solo by Bill Bruford, I have used this as a reference for impact and many amps just cannot pull it off, I often find myself reaching for the volume knob in order to reach the desired level…………Not so with this amp It recreates the effect with ease.
Beck Sea Change, A very well recorded album about breaking up, The amp portrays the emotion with startling realism………..One of Becks best albums just got better
Vocals reveal different pitches in what I considered well known, Steve Earl, Bruce Springsteen, Ray LaMontangue, Ryan Adams, Allison Kraus, Adele just to name a few.
The amp seems to excell at any quality recording I throw its way, It also seems brutally honest in its presentation of the source (crap in = Crap out, no warming the edges here.)
Strings reveal the pluck, the body and the decay, Cymbals reveal strike and decay and just shimmer with no static, or sizzle, Piano is very realistic. I cannot recall ever hearing acoustic guitar so realistic (short of being there.)
Build quality is second to none, very robust and solid construction with stunning wood work.
If you are looking for a reference level amp you owe it to yourself to call Justin who can fill in all the details of the build, His number is listed on the web site, when you call you get the builder and he is one of the nicest people you will come across.

Recommended for anyone looking for an endgame tube amp with some midrange magic and transient mojo.
AudioExpress RMAF 2016 – ampsandsound coverage Ampsandsound from Southern California (www.ampsandsound.com) teamed up with North California Sonic Studios to show their latest, hand-built hollow-state designs, the $3,600 Agartha and the $1,850 Leeloo combination amps. The former pairs a 6SL7 up front with an overspec’d power supply and 300b triode on output. The latter is both headphone and power amp,using a 12AX7 or equivalent for input (see Photo 8). With a pair of EL-84s out to deliver 2.6 W into an 8 Ω speaker, little Leeloo will also drive a 32 Ω headphone with a dead quiet 1 W of hollow-state […]
