Best amp under 150$?

post #1 of 12
Thread Starter 

i was looking to buy a portable amp, im looking at E17 because it has a DAC as well, but are there other amps that allow two headphones to be plugged just like the E7's?

Do two persons need to be able to listen at once?

 

Obviously your options expand if switching between phones is a possibility.

yeah are there any good ones around 150 or less that 2 people can use at the same time?

Both Rolls and Behringer make inexpensive, professional headphone amps which allow more than one connection at a time.

Which models?

Unless you both agree on the volume level, having two outputs might not be what you really need. You might consider a splitter cable and use it to drive two amps. That will give you two volume controls, twice the battery life, and not have any issues with the impedance the amp sees dropping because of the headphones in parallel.

i agree, but are there any other models which have 2 outputs anyway?

The Rolls HA43Pro has four outputs with individual volume sliders. Each output has 3.5- and 6.3mm connectors. Behringer and I think Pyle make similar pro equipment.

Why you need two headphones plugged in at the same time? I am just wondering if there is a downgraded sound quality because of that.

Because it would be useful to share music. Headphone splitters don't change the sound at all do they?

They do, but a well-designed splitter's only effect will be a loss of ~1.5dB in volume. That's nothing that can't be fixed by turning up the volume a little bit.

It depends on your amp -- the impedance seen by the amp will be less than either of the headphones provides - about half if they are the same. When the impedance of the load drops, not only does the amp have to put out more current at the same voltage level, but the internal impedance of the amp may come to be significant, potentially "muddying" the sound. If you want to know more, a good search term would be "damping ratio" or "damping factor"
