Another benefit with Class D Audio
I just yesterday completed converting one of my Class D Audio CDA 254 amps to three-channel, through installing another CDA 254 amp module and an additional RCA input, and positive and negative speaker terminals for the single channel.
The transformer and power supply provide plenty of power for the additional channel, and the power supply board comes with additional terminals for wiring the extra amp module.
At 500 Watts into 8 ohms, my KEF Reference 100 center channel has never sounded better ( you ought to hear how a baseball sounds coming off the bat of Nelson Cruz!)
This modification was $194, and I couldn't be happier with the results. Not only do I have my other CDA 254 back for use on my Tannoy front speakers, I am able to get back to using my great SET 300B for special occasions.
As stated in other threads, I am not a shill for Class D Audio, just a very happy customer.
