Abrahamsen V2.0 UP discussion

The small 70Wpc in 8ohms V2.0 UP doesn't seem very powerful when you see the rating. We also know they have massive power supply, but how big is big?

Let's calculate the energy that can be stored by the PSU for short bursts in transient peaks.

E = 0.5 * C * V² measured in Joules (J) of energy.

A typical integrated amplifier would have a power supply with around 20,000uF at 63V.

E = 0.5 * 0.02F * 63V² = 39.69J

Now, the Abrahamsen V2.0 UP and the power amp version V4.0 UP.

E = 0.5 * 0.1F * 80V² = 300J

A defibrillator used to revive people with cardiac arrest shoots 120J-200J through the pads. 300J is for very very very dead.

Wow !

Perhaps Colin should offer an optional set of compatible defibrillator pads and gel as a package with the Abrahamsen amps, then if a customer suffered a heart attack due to over excitement caused by the incredible dynamics and sound quality they could be revived quickly and get back to listening .

Perhaps the NHS might be interested in a trial unit, they are bound to be more cost effective than the current units and could double up as a music system to soothe the patients back to health as long as nothing too exciting was played to avoid damage to anyone with a weak heart . *smile*

I wonder what gel thinks about this. Could be a great career for him to tour the UK with Ambrahamsen amp in a backpack, reviving audiophiles from Tom Evans preamp fires. Defibrillators are just charging and discharging a bank of capacitors, so you can convert the Abrahamsen v2.0 UP to a defibllirator literally.

And I think this thread has gone horribly wrong. *help*

I suspect that you may be right. *yes3*

I am sure Gel would be up for it though. *wink* *i-m_so_happy*

Me too, as I think as well as the Abrahamsen he'd have to lug a power supply of some sort.

All feather light 55 kilos of it.

Sorry I just had to get the last link in somehow .

I'll stop it now. *biggrin*

Might as well link the poor guy to a trolley.
