The BYOB Amplifier
If you have read the previous chapters you will not be surprised by the looks and the design of the BYOB - Bring Your Own Battery - Amplifier, as it is just the application of a fundamental concept:
Good sound is the absence of distortion mechanisms.
As well as happyness is our basic nature and is present as long as deteriorating conditions are absent, a good sound is nothing but the avoidance of distortion mechanisms.
So let's take a look on the special features of the BYOB amp:
Nittiy gritty features of the BYOB amp:
Price and Ordering Info
One Altmann BYOB amplifier comes EUR 1500,- including 5 years guarantee, quality battery cable (shown below), manual and worldwide shipping (air parcel).
Please order your Altmann BYOB amplifier through this email.
The performance standard of the Altmann BYOB amplifier IS A PERFORMANCE STANDARD.
The BYOB amp sports 2 x 10 W into 8 Ohm respectively 2 x 20 W into 4 Ohm and even more into 2 Ohm. This high power-level is achieved through bridged operation. That means, both channels are internally bridged by design.
The Altmann BYOB amp is an audiophile amplifier, not a stadium PA amplifier. The power level is more than enough for home use and small to medium parties.
One channel is able to drive 3 'Voice of the Theatre' speakers in parallel. In other words, with the proper speakers (i.e. 6 VOT's) you'd be able to power a disco with it.
If you have high-efficiency speakers you can listen very very loud. Remember that the BYOB is battery powered and thus is not afraid of a speaker's impedance dip. The power is delivered instantaneously.
If you have low efficiency speakers, you don't want to listen very loud anyway.
The next time your car battery needs to be replaced, don't throw away your only source of clean power. If it can't turn your car's starter motor anymore, it is still perfect to be used with the BYOB amp.
I personally use a 10 years old Optima Red Top starter battery, which is a non-spillable high-quality high-performance battery. With one charge I can enjoy extensive listening for 2..4 weeks.
For charging, I use a standard battery charger. Most of you already have a car battery charger. If not, it's not expensive and a good thing to have... Good chargers are available from Einhell.
Battery Charge and Sound
An interesting feature of the BYOB amplifier is that the sound character is related to the battery charge. With a fully charged battery the sound is tight with explosive dynamics (can't get that with any other amp), while with a low battery charge the sound character resembles that of a no-feedback amplifier, very laid back and relaxed.
However, regardless of charge level, you will notice the absence of distortions that you were unable to identify or even name before.
Another interesting sonic character of the BYOB amp is that of integrity. The musical performance will reach you undivided and intact -> AS ONE. You will know what I mean when you listen to it.
