Harbeth SHL5 vs SHL5 PLUS

Hi Guys,

Seeking feedback on sonic differences between the two. Woofer and crossover changed. Have heard that there are differences in bass quality. My main concern is midrange and high frequencies. What are the differences? If there are...I am seeking the one with a smoother, more relaxed top end (non etched...eg...less leading edge and more body in vocals/string instruments). Thanks so much for your help.
@everyone....thank you so so much for your help. Large full soundstage and vivid image/instrument size is very important to me...besides having a smooth/relaxed top end (excessive HF hurts my ears and gives me a headache as I am extra sensitive to it). Has anyone compared the SHL5 and P3ser side by side before? I have not auditioned the P3ser before. Image/instrument/voice size almost the same? Thanks.
I listened fairly recently to the Super HL5 Plus hooked up to a mega-buck Naim rig. In the treble the sound was definitely not what I would call forgiving, and I didn't pursue the audition for very long. I have no way of evaluating his opinion, but the salesperson stated that he thought this model to be the least forgiving in the Harbeth line.
The P3 is a scaled down version of the Harbeth sound. I think you will notice it in a small room. I would say the C7 sounds more like the SHL5 than the P3. The P3 is more involving but you will miss the fullness.

I ran the Naim Nait 5i2 and Harbeth combo for a while and there was not a hint of brightness. In fact it sounded a bit rolled off on top. The bigger Naim stuff is more forward though.

If you use Naim, best to use their wire and interconnects.

I auditioned Harbeths using largish Japanese amps from Accuphase, Marantz and Airtight. I use a 100 wpc Yamaha. With these amps and using modest wire from Kimber, Atlas and Oyaide, I have never noticed brightness.

That said, both the M30.1 and SHL5 are highly resolving so if you have brightness or edge elsewhere in the system, they will definitely reproduce it.

Best to go find a place to listen for yourself. BTW in Canada Harbeth speakers are sold at full MSRP - no discounts - although I did get a good break on the stands.
I have owned the C7 and the P3 and had them side by side in my 20 x 15 size room hooked up to 70 watt Quicksilver tube amps. All I can say is I thought the smaller P3's blew the larger 7's away. The P3's just seem to disappear when used in a smaller room. I also found the bass on the sealed woofer was better and I never thought a sub was needed. You should give the 3's a listen and they just might surprise you!
Thanks everyone for your input. One more question...I heard that there is a difference in sound between finishes for the SHL5+...for example...between cherry and rosewood.
