Hi,
I was thinking about buying a cheap integrated amp to use as a temporary headphone amp. I also want to use it with speakers in the future. I would be using it with my Marantz CDP. My questions are this;
1. Can an integrated amp be used without speakers wired up, just solely with headphones? (I've heard mention of integrated amps smoking and overheating, etc. when speakers aren't attached, but maybe that was the 70's or something, old amps and stuff).
2. The amp's headphone out says 250 mV into 32 ohms. Is that powerful enough to drive beyer dt 990 (250 ohms) ?
3. What is the difference between mV and mW?
Any help would be appreciated, thanks.
