Speaker recomendation

I absolutely agree that it is best for the OP to use a high sensitivity speaker. The Legacy Focus may work, but I don't consider it's sensitivity to be high. The spec is stated as 95.4db (2.83V @ 1m), however since it is a 4 ohm speaker, this is a 2 watt rating. The 1 watt rating should be used for comparison to 8 ohm speakers, and that is 3db lower or 92.4 db. This may still be too high. Stereophile reviewed an earlier version of this speaker that was spec'd at 96db (2.83V @ 1m), but measured 94.5db (2.83V @ 1m), so an actual 1 watt rating was 91.5db.

Using a high sensitivity speaker will increase the probability of accurately reproducing the wide dynamic range of classical music in a large room and also allow use of the current amp, Moon 340i, to achieve this. For that 10k price, IMHO, this should be on the list to consider.

Retired now, but worked in the audio industry for over 25 years. Remember that average speaker sensitivity was 88-90db, with 85db considered to be low and 95db being high. The industry average may have shifted, I don't know, however the relationship of amp power and speaker sensitivity to achieve volume and dynamic range remains the same.

During that time, I was fortunate to be exposed to so many different products and setups. Heard Legacy speakers a few times and had a friend with a pair. Did they sound ok, sure, but never seem to be special, the goose bumps or making hair stand up thing. Some other listening experiences were impressionable and hard to forget. And please understand, this is just my opinion.

As far as the "having a bigger hammer" thing, I'm sure that appeals to many, but not me. I prefer quality over quantity. I never get focused on bass and treble, like so many do. I want the best midrange with a good balance of everything else. Basically, a speaker that doesn't have a strong point, but does everything well.

Absolutely, the OP needs to take a listen, but to as many speakers as he can.

And a joke for the day.
