Pass Labs X-600's vs. XA-160's

Forgive me,the Nemo brought to mind the Neo Classics.With the price of the 600s here on AGon.They might not be a bad choice.I have also seen the Lamm M1.1s fairly cheap.The 600s are balanced only,does that affect your choice?The 160s offer both,I believe.The 600s prefer a slightly warmer midbass and high frequency character upstream of them.Maybe a tube pre???Non silver ICs??

Tpsonic, Forgiven, of course. Your right about the 600's, they are expensive, so are the Nemos. I'm using a Pass X1 preamp, so running balanced is fine. My Dalis have a more neutral mid-bass, but I think the hi's are a little extended. Thanks again for your input.

I must politely disagree with Percon. I have been using Pass gear in my home music systems for about the last 8 years. I have had both Aleph and X-series amps and preamps. Currently, I use the X1 preamp into Pass/Volksamp Aleph 60 mono amps (considered by me and by Pass to be one of the best sounding circuits he has ever designed). The Aleph monos handily drive Quad 989 electrostatics, with a stereo pair of Vandersteen 2Wq subwoofers asisting below 80 Hz. To make a long story short, the XA series should produce the best of both worlds (as Pass says, "like peanut butter and chocolate..."). I say "should" because the XA amps are the one thing made by Pass that I have yet to hear. Nevertheless, I have had all manner of costly tube gear and other stuff in here, and nothing surpasses the purity of tone produced by the pure single-ended Class A circuit of the Alephs. And yet...there is a sense of speed, transparency and spooky dynamics with the X-products that is addictive. So, why not have the best of both? If you can afford it, that is. There is one other factor to consider, I suppose, on the level of personal responsibility. The Aleph and XA series amps are exorbitantly wasteful of electrical power.

I hope this helps.
