I was seriously purhcased when I recently bought on flea market those speakers for quite a bargain of around £70 together with some old CD sony player.
The JPW were in almost spottless condition, but even bigger surprise came when I connected it to my hifi system at home.
The sound is quite open and detailed with both extensions quite deep. The highs and cymbals sounds not constricted, lively, vocals are natural and open. Bass is deep (maybe due to quite heavy weight) of the speakers. The sound is spacious and speakers are easy to drive, good match for many amps. I tried it both on my old Sony amp as well as Musical Fidelity.
I am happy with my purchase as this is my first JPW experience, I already spent few slepless nights when listening to them ;)
the build quality is excellent too, build and made in England, and they sound as english loudspeeakers too.

The JPW ML710 made it onto my shortlist of speakers a year ago. I purchased the Tannoy Mercury M2s instead, but I could just as easily have gone with the ML710s. I listened to them often and liked them every time.
The ML710s are attractive floorstanding speakers veneered in cherry with a black baffle. They follow the standard layout of one inch dome tweeter mounted above a 5 1/4 inch woofer, ported at the rear. The speakers were spiked and heavy.

The first thing that I wanted to know was how such a slender column and small woofer would handle bass. I played several tracks from Maxwell's "Maxwell." The bass sounded full, extended, rhythmic, and wonderful. The ML710s really got into the groove. Maxwell's vocals sounded clear and accurate.

Following Maxwell, I tried a couple of Mozart's piano concertos and liked what I heard. The piano tone was shiny and involving. The orchestral accompaniment was clean sounding and nicely timed. Orchestral textures were delineated well. I heard no blurring of transients. Overall, these Mozart concertos sounded very crisp and lively on the ML710s.

I later tested the JPW ML710s with a bright recording of Prokofiev's "Classic" Symphony. I listened for shriek and harshness. The strings sounded lean, but not unpleasant. I find that the ML710's design, consisting of a small woofer and dome tweeter in a narrow column, does not give orchestral strings much bloom or richness. I have heard this with dozens of similar designs. While lacking tonal body, the ML710s did present alot of the texture of stringed instruments, bringing them to life a little bit more.

The ML710s sounded best with a dynamic amp. The dealer hooked them up to a pair of Marantz MA500 mono-blocks that controlled the speakers well. I found myself pleasantly surprised by the ML710's sound, which I would characterize as slightly lean, but tuneful, lively, and involving. Moreover, the ML710s display a rhythmic, extended, and groovy bass.
