Building amps and assuring water resistance.
- Jun 21, 2001
I as some of you might remember was investigating the Possibility of A class A Portable Amp at that time I was Thinking the EL-2009 at 63 Ma a farly good Class a range for most Headphones. However i run across a buffer that when stacked give 400 Ma of output Current (unprotected i might Add) and consume about 40 Ma per the Stack of 4 about 20 Ma Ea. Still good Class A. BUT the big suprise in in the Listening. Using the AD-8610 as an opamp this AMP Defines Clarity and refinement. I would Highly sugest this combo in a Multiloop comfiguation. I was flat Impressed and i as you Know listen to Great sounding Amps. This is as close to sonic Perfection as i have yet to hear out of any Audio Electronics. I am sure a Dual mono or Mono Block Version of this will perform as well or better as any solid state Headphone Amp Available. Oh Ya it Also Runs on batteries. Separate ones for each channel. Thanks tomo for the Toy car Battery Tip. see hear for the Buffer. http://www.intersil.com/design/param...?pn=HA3-5033-5 This is good.For Burr Brown Fans This http://focus.ti.com/docs/prod/produc...tNumber=OPA633 is the Same thing as theHarris Part.
