Move from my LS3/5A orig ownr to Harbeth which

You should try to listen to Tannoy Turnberry SE. It may be more expensive but it sounded sweet, detailed and not harsh at all. Typical british sounds just like harbeth.

With that size room I would go with the P3's. I have them and with the sealed woofer you don't have to worry about placement. I am still amazed of the sound they produce!

The 30.1's are quite overpriced in US, but others will opine "whatever the market will bear" or "..even at the price a bargain" - well la-de-da for them, most of us aren't professional reviewers or insiders who get a price break. Betcha in less than two years you'll find some here used at price that makes much more sense. Patience is not only a virtue but can save you a chunk of change as well.

Thought I would try something different....Use older paoli SOB amps to drive with a paoli preamp....Sometimes switch to my esl-63's. The Rodgers are quite nice...look foward to hearing the Harbeths at an upcoming show

I started on a pair of Spendor 3/5SE's and upgraded them to Harbeth M30's about two years ago. I drive them with a Cary SLI-80 integrated tube amp and use a REL T5 sub. This combination totally satisfies me (finally). I also listen to vinyl mostly and some digital as well. The M30s are the best speakers I have heard. I've compared them to other speakers selling as high as $15,000 and have not liked any of them in comparison to the M30s. I would not say they are over rated, but they are not for everyone. They are designed to reproduce sound as it was intended to sound and nothing more. Some people don't want music to sound that way. It's completely subjective so if your ears prefer an accurate and somewhat polite presentation (as mine do) then you should be very happy with the M30s. FWIW, I have not heard the 30.1s yet, but I have been so happy with my 30s that I do not feel the urge to upgrade. The 30s are available on the used market for less than $3000, which is a bargain IMO.
