Is there a point of diminished returns with amps and Harbeth 30.1s?

I would see if the Cable Company has any more Audience AU24 show demos at 1/2 price. Excellent sound and very easy to work with.

FWIW I have used AU24E with my 30.1 all along, and have been quite happy.

Thanks for the suggestion re: AU24s. I use the Audience Ohno already. While there may be a big difference, it would cost an arm and a leg because I need 5M runs. Seems like the best money is still to be spent on an amp.

@dhcod - I absolutely hear what your are saying, but after trying some better cables with several Harbeth speakers and hearing the dramatic results, I think you are closing yourself off from a possible big upgrade. Your system is very nice and I’m sure well-tuned to your tastes. IMO, you should at least borrow a set of cables from the Cable Company and try them. This way you will know if the Ohno is the bottleneck. No other way. I think you might try the Purist Poseidons or the AU24s, as I have heard them both and they sound amazing with Harbeths. I have had systems where 10 gauge Beldens worked fine,, but others in which they left a lot to be desired. So that’s my opinion and the rest is up to you. Who knows, you may luck out and say the Ohnos are just as good and move on. Or you may find that the new cables brought sonic upgrades beyond what you thought.  

Very interesting perspective! Thanks. I will check out cable co and see what they have to loan. Certainly worth a try!

Very logical and wise suggestion from @chayro . Little  (If any) risk involved. The Cable Company is an excellent resource for allowing the opportunity to hear and compare cables in one’s audio system. In some systems and with certain audio components, cables can provide very notable sonic improvement. If not, return them.
