Hi all

I want share one phenomenal product from Altman Germany , like already more popular dap

player Altman Tera , Altman produce very excellent 12 volt car battery : the BYOB Amplifier

The BYOB Amplifier can be used as hone integrated amp and headphone amplifier

Please see the information below :

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:

Conforming to the Vibration & Character chapter the BYOB amplifier has no enclosure, and thus no enclosure resonances. If you knock on it, you won't hear trashy sounds. Just the musical sound of a solid spruce board, that is lacquered with natural wood resin.

The circuit board is small in relation to the spruce board and it is tightly fixed flat on the board, so it cannot vibrate in its own fashion, but is connected to vibrate with the - Mother of Tone - character of the lacquered spruce board.

Board sits on 3 lacquered spruce feet.

The power source is a single 12V car battery sporting independece from noisy mains current and HF rectifier bursts, as explained in the Air and Current chapter.

All connectors directly soldered to the circuit board -> no cable / wiring effects.


Nittiy gritty features of the BYOB amp:

About 2 x 10 Watts of Power into 8 Ohm or 2 x 20 Watts into 4 Ohm or even more into 2 Ohm.

Wima coupling caps.

Volume control with black anodized aluminium knob.

Blue LED indicates operation and charge status of battery (bright with full battery, off below 10 Volts battery voltage.

Power switch and 10 Amps fuse.

Gold plated connectors for input (RCA) and output (banana / cable).

Polarity proof power connector.

Specially treated spruce-board from sustainably managed forests.

5 years limited warranty

Made in Germany


Price and Ordering Info

One Altmann BYOB amplifier comes EUR 950,- including 5 years guartantee, quality battery cable (shown below), manual and worldwide shipping (air parcel).

Please order your Altmann BYOB amplifier through this email.


Performance

The performance standard of the Altmann BYOB amplifier IS A PERFORMANCE STANDARD.


Power

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.

Batteries

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.


Experience Oneness

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.


Applications

1) Audiophile Ecstasy

Ultra-Audiophile performance, ultimate precision, natural sound with explosive dynamics, uncompromised groove.

Standard version is hi-gain, tube-o-latored. Lo-gain version also available.

Easily driving low impedance speakers.

Signal path length: 10cm (4 inch) from input jack to speaker post.

3) Recording and Mastering

The Altmann BYOB is the most transparent amplifier, at least on this planet.

You will encounter the true dynamics as well as the tiniest harmonic detail of your recording project.

Absolutely uncolored sonic performance, independence from noisy mains, extreme precision and freedom of sonic signatures. Rack-mountable versions with 2/4/6/8 channels available.

This is a joke right? Definitely ridiculous, but is the functionality worth 950 euro?

Like Charles Altman Tera player has excellent sound quality
His amp BYOB amplifier sound very good to , that s why I call phenomenal

For the price they are charging you would think they could throw in some kind of box...

 

They say it is the most transparent amplifier on the planet. Dunno about the sound but it sure looks transparent. Please institutionalize me the day I pay EUR 950 for a spruce cutting board, a few parts on a circuite board (what looks like a cheap volume control) and a "quality" car battery cable. On second thoughts, just shoot me.

"Hello

Ive build a clone of this amplifier without the pot.The Amplifier is based on the Thomson TDA 7374 Chip.The chip costs 3 Dollar in Ebay or at Reichelt Electronic Germany.Ive build the amp on spruce wood board with Black Gate power supply caps and Mundorf silver in oil coupling caps. Belive me Charlize is in another league, better in all aspects.Its the same dillema with the Altmann dac.A good dac but Monica is 2 steps better.

I hope I can clarify things

Regards Tony"

I love how he lists the way it changes character depending on battery voltage as a "feature".

 

I heard one of these years ago and it was a good amp if lacking a bit in prat. The battery as power source is a bit of an issue here. We tried  a 10,000 mF cap put across the rail to speed things up a bit and the owner continued to use it that way.

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.

I feel sorry (not) for people that shell out the money for this.

You really gotta be kidding,...right?!?!?! This isn't gonna be another one of those FOTM pieces of garbage, is it??? I mean, it's garbage now,...really,...rolleyes.gif Any time a person claims something is "audiophile" shills pop out of the woodwork like a busted termites log. This thing is CRAP!!!

Cmon... at least you got to admit that the thing is transparent. You can see the audiopile grade components clear as day.
