ls70 an chip alternative

tadiam1 · 26th April 2010, 02:10 PM

I have an old ls70 polk loudspeaker an want an alternative (chip amp) for my speakers.
No power quality

I use the lm1875..work well but need an more clear sound

Similar to my 10w class a amp

Similar to your class A amp but small, cheap and easy?

How about a free lunch as well?

You've already tried what is arguably the best sounding chip...
