I'm intrigued by the idea of building a SET power amp, and I'm wondering if the GSG is sufficient for my needs.
I have Energy RC-30 speakers, sensitivity 89 dB (anechoic), nominal 8 Ohms, minimum 4 Ohms. I know that this sounds marginal, but: I'm listening at moderate levels, have a powered sufwoofer crossed over at 80 Hz, and plan to connect the GSG to the pre-outs of my Denon receiver. To put things in perspective, the power amp section of my Denon receiver is rated at 75 Watts (RMS per channel), and its volume control is typically at 40 dB below full scale.
Could a GSG work and will it sound good?
