High End Edelweiss - 3 Preamp+ and Hercules - 3 power amplifier prototype
Anatoliy Lisovskiy
Are you struggling with High End sound quality problems and cannot find answeres? Let me help you.
A new version of Hercules prototype, almost ready.
Class A1 push-pull amp, 45W per channel.
Unbalanced RCA and transformer balanced inputs, 0 dB.
4, 8, 16 0hm speaker outputs.
Continuous variable damping factor cоntrоl, from negative output resistance (active servо-damping) tо positive (current drive). Almost inaudible soft saturation when overdriven.
$4,800 fоr the prototype. When the production will be available, unknown.
I have pre-production preamps, if somebody is interested. Power amps will be available later.
Preamp+
4 switchable stereo inputs, RCA outputs, 2xTRS outputs for headphones.
12 dB maximal gain.
Stellar quiet, tremendous headroom from RCA outputs.
$980 for a pre-production assembly.
Either 120V transformer for Americas, or 240V international.
The next version will have additional gain control for RCA outputs, from -6 to +12 dB
It is still a preamp, so please do not expect it to drive on full loudness planar magnetic headphones that demand power amplifiers! It is a pristine clean preamp that can easily drive dynamic headphones.
Lead time - 2 weeks
It uses USA designed and made 8AL9 tubes that contain medium - mu triode and high gm frame grid 10W pentode that was needed for fast linear video amplifiers in latest tube TVs.
