If you’ve purchased the new iTouch from Apple you’ll find tons of impressive features however, output level is not one of them! Perhaps the lowest output level of any MP3 player made?
You’ll be pleased to know that using it with a ZenHead portable headphone amplifier turns it’s very unimpressive sonics into a dynamic and textured performance that is of good enough quality to be enjoyed by any audiophile!
The iTouch has such a low max volume that even most headphone amps can’t get it loud enough to enjoy and if you find one that did, it would be too loud to use safely on everything else. The ZenHead has been evolving internally to now have adjustable gain, adjustable input impedance, and the cross-feed can be turned on or off via some high quality internal switches. This makes it easy to set up for the wide range of sources it can be used with!
