Break in period for DAC

[mhw100]

Just replaced my v20 and notice the new unit isn't quite as loud. Is there a break in period for the DAC?

It's electronic, it's not like a car.

Nope

I wouldn't have thought so either. Why would the same music file and same headphones produce a lower volume when the high impedance mode is on? Could one of the 4 dacs not be engaged?

I know the B&O ear buds occasionally tripped high impedance at first because of a leftover manufacturing oil or film on the plug that would wear off and stop tripping high impedance. So I guess it's plausible something like that is happening with the new phone's jack, which may wear in over time and make a better connection. Just a guess, though.

Headphones and speakers have a burn in period. Tubed equipment would be affected over time and also have a warm up that could affect sound. The Quad DAC should not have a Noticeable affect with usage.

The high impedance kicks in because of resistance in the circuit so a bad connection would make the amp gain higher.

When you say lower is that with high impedence on verses off on the same phone or are you still comparing to your prior phone?
Also are you doing a side by side comparison or from memory?

I want insinuating that it was the exact same issue as the ear buds, only that it may have been something along those lines.

Understood.... I was just clarifying that a poor connection like the B&O because of a protective coating would have the opposite effect.
A real bad connection of course would cause a different set of symptoms.

The volume seems lower on my new v20 vs old v20 when high impedance is engaged in both cases playing the same song on the same headphone. I am going by memory as i had to return the old v20.

Is the gain set at the same levels it was set for your previous phone? When the quad DAC is enabled, you can add up to a 6dB gain for each channel. Maybe it is set lower on your current phone.

The gain is the same but thanks for the thought.
