Harbeth HL C7 ES

Chris, your responsive comments are correct, of course. They sound great with tube amps but need a significant amount of power to do their best.

But, although they are revealing, they are forgiving of subntractive weaknesses. They sound nice with just about any decently engineered amp or cdp from the most inexpensive budget components on up. They just sound better with better. Now, if there are any additive anomalies or glaring weaknesses in the chain, they'll certainly let you know about them.

Thoughts on cables? Risky question hereabouts. Maybe we'll get away with though. The dealer from whom I bought my C7's a few years ago, Signals in the UK (email order sound unheard) carries Nordost cables, but was not enthusiastic about the combination of the Flatline Gold and the C7's. He recommended the Blue Heaven as a better match. I use something completely different, AQ Crystal 2 (or +, I forget) as I think I prefer a somewhat softer presentation than I understand you get from the Blue Heaven. It may just be a matter of taste and your cables might suit your ears just fine.

Now, and here's where I expose myself; the Harbeth speakers are very revealing in the midrange, really astonishingly clear, and very neutral on top. To me, therefore, they are very revealing of really subtle differences in cables. You can drive yourself nuts trying out a bunch of different cables. If they sound good to you with what you have, leave well enough alone.
