Charles Altmann BYOB amplifier
A 4-year old BYOB amplifier from http://www.mother-of-tone.com/byob.htm
The Formula One
of amplifiers. You don’t pay for chassis, unneeded connectors, switches, power
supply. You just pay for circuit design, parts choice and violin varnish
It is powered by a
12V battery (a car/caravan/boat battery, deep cycle is preferred) which, even
with the battery charger included (but don’t you own one already?), will cost
you a lot less than ‘audiophile’ power cords and power conditioners.
The only amp I heard which beats the BYOB Altmann amp was
the ASR Emitter (US $25,000 in 2006).
This amplifier has enlightened my music playback experience
until last month when I indulged into a new multi-way system which asks for
hundreds of watts of power.
The BYOB amp is capable of 10W/8 ohms, up to 20W/4 ohms.
I used it to power my Spatial Audio M1 Hologram (100dB
sensitivity) to concert level with 100% accuracy due, in part, to the battery
(pure DC) power supply.
This amp can only be bought from its manufacturer, ie
Charles Altmann, at the current price (2018) of 2990 euros = AUD $4670 = US
$3500. It is extremely rare to find it on the second-hand market.
Can ship anywhere to buyer expense. Can demonstrate at my
I’m the first owner. I’m asking for AUS $2000/US $1500 but
I’m ready to consider any reasonable offer.
