Audiogaby,
it was a Stealth HAC. Keep in mind I do not have extensive PC experience, this was my first 'gee, PC's do matter' moment, so there are probably better matches out there (which, btw, if anyone knows of please let us know!)
Still, it was a nice improvement, even the wife noticed (so I knew I wasn't totally crazy). For $70, used, it was a good deal.
As an aside, I should add that the Absolute cord was brand new when I tried it, if that matters.
Hope this helps!
