Mo' is better
Yes, I am guessing that more amperage is better, but do we know if there is a break point? Most say that 12V is too low, 20V is best, 24V is too much. Is there a similar rule a thumb for amps?

trikster,
Below are the plans for the bucket sub which like the TPA3116 is another inexpensive audio triumph. I think I started a thread here on them.
I added one important feature: a plywood ring under the bucket baffle to mount the drivers to. I special ordered the 5 gallon buckets in black from Home Depot as it's almost impossible to paint plastic buckets and get good results.
My speakers are bass reflex using high efficiency 4.5" Fostex drivers. You can find all the enclosure plans for the Fostex drivers free at Madisound. If you haven't heard crossover-less, full range single drivers you're in for a surprise.

Nice looking combo, Lacro. What speakers are you running?
X-LS Encores
Lacro,
Are you getting any thump on shutdown?
Have you any idea what the "mute" is on the board?
I'm not really a believer in "break-in" of electronic components, but, in any case, one of the two twin-chip amps has been in use for a few months now.Drew_t.
have you given the board / pot of the board some time to settle ? My current shunt style "pre" (to TPA3116 board) has taken awhile awhile to sound decent. For some time i have had rolled off highs, thick bass and quite a narrow sound stage.

I tried a different pair of speakers today with the twin-chip, just to rule out the Polk RTi4s as being the cause; same lack of top end sparkle noted.
