The audiofool mental condition in full display.

When I see such "neatly" laid out PCBs with components grouped and mirrored, I find myself wondering whether performance has been left on the table, where a less aesthetically pleasing design optimized for performance (wrt trace routing and isolation) would measure better.

The NC-250MP has better all-around performance (lower SINAD both at low and full power, lower crosstalk) compared to the Vidar with similar power output and lower waste. An amplifier cannot be "overpowered" for any pair of speakers, assuming it has correct gain to match the source output. You...

Does the ADC portion really start to saturate above 0.8V? That's a very line input low voltage, esp. for automotive where 4V or even 6V audio line outputs are common.

Wondering how it would perform with a Purify 6.5" driver in it. Through I would imagine KEF would never use such a "weird" looking driver since they put too much emphasis on exterior design.

What are the audible benefits of that?

After contacting Audiophonics support, I apparently learned that you can use a custom USB to TS jack lead (3.5mm mono, +5V at tip, GND at sleeve) to trigger the amplifier on and off via display or computer power status. The rep assured them trigger function is "totally disconnected from the...

Your subjective perception of the amplifier's performance.

It's not the amp that's the problem.

Just an update, my amp is now almost two years old and keeps humming along without issue. I don't turn it off either (due to inconvenient placement and laziness), it's left on 24/7.

Wrong.

Well, unless you have an AV prepro ($$$$ and questionable performance), a miniDSP 2X4 ("OK" performance according to an early review by Amir) or one of the very few subs with high-pass outputs (questionable performance), a powered sub won't take some of the load. 2.1 bass management solutions...

No.

What other options do I have?

I want to manage 3 outputs, 2 outputs as stereo to my DBR62s and a mono output to my subwoofer.
