av98m 0 Report post Posted October 15, 2003 (edited) Somehow I felt compelled to post this picture.... Yes, thats actually an Airhead(with *gasp* batteries!) hooked up to a full sized CD player (sacriledge!! ) Edited October 15, 2003 by av98m Share this post Link to post Share on other sites
N@Z 0 Report post Posted October 15, 2003 That's how I started into headamps as well with a pair of Grado SR80. Plus HD600 & ER6. It all went downhill after that! Share this post Link to post Share on other sites
Rameish 0 Report post Posted October 15, 2003 Most portable amps like the Airhead, PC2 do have the ability to be powered from an ac-dc adapter. Others like the Mint and META can be built to have one. The main issue with using a portable amp in the home setup is gain. The portable amp has high gain to accomodate the low output (usually 0.6 volt) of portable players. Home CDPs tend to have higher outputs (usually 2 volts) hence the amt of volume control is rather limited. My 2¢ Share this post Link to post Share on other sites

My 2¢ Yes, I find setting the volume level is a little bit trickier with the Airhead when hooked up to the CD player. Slightly OT, I was wondering why my Airhead recently seemed to be noisier when using dc power, but fine on batteries. Then I saw the surge protector posts in the solid state thread, took a closer look at my newly purchased power strip, and noticed for the first time the words surge protection on on end. I switched to an older power strip with no such markings and problem solved, no more extra noise from the Airhead. Edited October 16, 2003 by av98m Share this post Link to post Share on other sites
Rameish 0 Report post Posted October 16, 2003 Surge Protectors normally suck big time and are for computers - computers don't give two hoots about noise. Generally get a linear regulated AC-DC converters (not the switching types found in most lap top AD-DC converts). Share this post Link to post Share on other sites
N@Z 0 Report post Posted October 16, 2003 My Airhead suffered from clipping when used on my CDP. No such problems with the Total Airhead or any of my other portable amps so far. Share this post Link to post Share on other sites

Mackie 0 Report post Posted October 17, 2003 Owners of cdps with variable output such as those by Marantz can lower voltage gain to accomodate portable headamps but I don't fancy the idea of adding a potentiometer in between the cdp-output/amp-input.
