Hello,

I'm considering buying a Teac 300DAB mini system, but keeping my old
Morduant Short MS3.30 speakers. The specs of the amp (AH-300MkII) say
"45W + 45W (6 1/2, 1kHz, 0.5% THD)". This means little to me, but I
guess that the 6.5 is the impedance, so the amp can do something like
35W RMS per channel to my 8ohm speakers.

Is this enough power?

45 watts into 6.5 ohms means the amplifier can produce a signal of 17v RMS.

Why not connect an AC voltmeter across your speaker terminals, and see what
signal level you're using? If it's less than 17v, the new amplifier will
drive your speakers as loud as your existing amplifier.
