RE: Re: Simple Multi Room Audio help

[Marcus Warrington <marcus.warrington@xxxxxxxxxx>]

I have some of these for my evolving whole house audio project.. they
are n=
ot bad, a little bass shy, but good sound. You'll need sensitive speakers
t=
o get really loud volume out of them.. they are only about 6Watts on 8ohm
s=
peakers. Having said that , they plenty loud enough for background/party
mu=
sic. Getting a decent 13.8V regulated power supply makes a big difference,
=
see http://www.maplin.co.uk/Module.aspx?ModuleNo=3D231&criteria=3Dbench%20p=
su&doy=3D9m2 you can easily run two, possibly three amps of the 7Amp
versio=
n.

The only thing is that they are now getting a bit expensive for my taste,
t=
he average price on eBay at the moment is about =A325-30 + delivery.

=20

At the moment I have 4 of them but only 1 in use. My plan is to (re)mount
t=
hem into a single enclosure (rack mountable).

I had anthoer thought last night - there's also these little amps
which get excellent reviews:
http://www.tnt-audio.com/ampli/t-amp_e.html
<http://www.tnt-audio.com/ampli=
/t-amp_e.html>=20

They're small in size and can run from batteries if needed, or from
mains (adaptor?). They were going for very little money but I haven't
seen too much discussion of them recently.

HTH,

Tim.
