What you're experiencing is the sound of Heritage Specials vs Harbeth. HS are overly detailed and can sound harsh and fatiguing, especially brand new out of the box. I've owned Special 40s and loved that speaker, even more than the HS. Harbeth are super pleasant sounding speakers, even on recordings that are less than perfect. Sorry, but this has nothing to do with the cables. I've owned HS and every model Harbeth makes, except for the 40 series. I liked the HS at first, until I realized I couldn't listen for very long, and the music became fatiguing, just like B&W. I would suggest pairing your Pass to a different speaker that creates a more satisfying presentation.
Speakers, speaker cables or I’m getting old…
I began listening to my gear as it filtered in from various spots in the US. I bought cheap cables, as I waited for my cabling to arrive. I have a set of Heritage Specials, ran from a Pass X150.8. I noticed right out of the gate at what I would call “moderate” volumes there’s a frequency that “smears.” I’ve never heard this in any of my setups, have just read others reference it. Now, what I’ve noticed is as my gear has arrived and as the chain improved, it reduced, but is not gone and I’m unable to listen at louder volumes due to it.
The one item that’s yet to arrive are the speaker cables, currently on there is what was available at the moment, something very thin and cheap.
My prior setup was Harbeth’s off PL, and am very familiar with that sound. I’ve ran PS Audio BHK Mono’s off a set off Dyn Confidence and loved that too. I tend to believe it’s not the speakers. But rather the cheap speaker cables…Or, I’ve aged 3 years since I’ve had a 2ch setup, and my hearing has changed and I’m just more sensitive to certain frequencies. For the record, I’ve always been rather sensitive to an upper mid/higher freq sound, it pierces my brain. B&W + Mac comes to mind…ran that once as well.
The other oddity is that older recordings, or older remasters like Tom Petty Wildflowers and the off shoot releases from it sound amazing. Dave Matthews sounds amazing, Radiohead, Willie Bobo, so there’s a bunch that doesn’t generate that smear or sheen. I’m using qobuz. Really, anything metal related, Tool, Lamb of God, Metallica is a little harsh to listen to and moderate volumes.
