Ampsandsound from Southern California ( 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 bliss. Agartha kicks out 5 W of triode power into an 8Ω load, and also 1.5 W into 32 Ω headphones.
