Those of you who saw our Enjoy the
Music.com Hi-Fi News & Record Review 1999 show report will remember the
killer cool colorful Nimis integrated tube amplifiers. Coming in five
gloriously fun colors like Blue, Green, Orange, Purple and Yellow, this tube
amplifier uses two EL84 tubes per channel to produce approximately 15 wpc.
Four inputs and tape output are standard as well. The entire amplifier
construction internally is more or less monoblock-like with the main exception
being sharing the main power transformer.

Seen above is a wonderful 3D rendering
by Kolja Tatic. While i wish it was a real tube amplifier, it is for now only
a beautiful dream. Maybe some manufacture will see the above image and hire
Kolja to visually design an amplifier for them. Until then we have the
glorious picture above... and a dream.
Hand-made to exacting specification in
Japan, possibly the ultimate 2A3 amplifier in the world could be none other
than the Audio Note Neiro. It features zero-feedback parallel single-ended
output stage with precision hand wound output transformer using age annealed
copper wire on both primary and secondary windings, silver foil signal
capacitors and all things tweaky. The hardwired circuit uses Audio Note's own
99.99% pure silver cable. The chassis is made from pure copper while the
critical power supply is valve rectified. The power is also choke filtered
while high quality audio specific Cerafine electrolytic power capacitors are
used.

Brought to us from reader Luis Borrego
is the Nestorovic Laboratories Model NA-1 Tube Power Amplifier. It is a single
channel amplifier (monoblock) with 150 watts power rating into either 4 or 8
ohms. The output stage employs a parallel push-pull configuration with loading
in both the anode and the cathode circuits. The input stage is also in
push-pull configuration, and has automatic self balance. This allows either
single ended or differential input configurations.
