Hey Matchstikman. I’ve gone down a similar rabbit hole with a new phono stage, so perhaps this may be of some help or at least some commiseration. I recently upgraded my phono stage from a Sutherland Insight (SS) to a Manley Chinook (tube), both using a Hana ML cartridge. My Insight went to a friend the day I got the Chinook. The Chinook is twice the price, so should have easily bested the Insight. But initially I had some buyers remorse. There were things I really liked about the Manley, especially the improvement in detail and soundstage, but I think it was also more revealing of issues in my system and with being more resolving, it showed some harshness on the top end, with some sibilance on some recordings. It is a used piece of gear, so break-in is not the issue. I went through a lot of trial and error to try to get things right.
First, cable capacitance is a thing, most importantly with the phono cable. As you’ve seen, different cables can help tune your system. I have been using a DSR3 (0.5m) with my Insight for years and it sounded excellent. Brought out a lot of detail and top end sparkle, while retaining all of the good stuff below. But on the Chinook, I ultimately found the high capacitance was too much. The DSR3 is listed as 923 pF/m. Steve confirmed that may be the issue for me. I tried a 1m length of Blue Jeans LC-2 cable, which is spec’ed at about 36pF/m. This tamed some of the “heat” on the top end, but didn’t resolve it. The problem was I found it to be muddy as well. Ultimately, I got a 0.7m length of 7N pure silver Audio Sensibility Signature Phono Cable. Some believe silver brings a more tipped up treble and can be thin and harsh on top, but the pure silver has actually been a very balanced and pleasing cable. It took a week to settle in, but I am very happy with the results and it made a significant improvement. These are spec’ed at 88pF/m. Additional tinkering with cartridge loading on the Chinook tamed things even more. With the cable swap, I was able to raise the loading over the recommended load settings for the cartridge and not have the treble get too hot.
Next I’ve been trying different tubes. I did try a set of Mullard PCC88’s and though they have sounded really good in my preamp and amp, they were not detailed enough for me in my phono stage. Maybe a tad soft. I’m working on fine tuning my preferred tubes now.
The last thing I tried that made a good bit of difference is to drop the input gain on my CSP3 a notch. I know it is generally recommended to use the input gain for adjusting volume for headphone use and otherwise keep it on max, but dropping it a notch didn’t seem to change anything on the volume level, but did in fact help tame the hotness quite a bit.
The other consideration is that I’ve had my cartridge for a few years and perhaps the stylus is wearing and causing some of the sibilance and harshness on the top end. The cable change, impedance loading, tube and gain setting changes have gotten me significantly closer to where I want to be than I was at the start, so I’ll see how things go for a while before thinking about a re-tip or replacement of the cartridge. I’m thinking I have a few good months or more left on the cart.
Steve mentioned the ZP3 can take 100-250 hrs to settle in and you said you have about 20 or 30 hours on it. I think you’ll find a significant change to the sound till you hit about 100-150 hrs. Glad you’re sticking it out before thinking about selling it off. You may be very pleasantly surprised at how things smooth out and begin sounding much better, with a little time on it. OTOH, It may turn out it’s not your thing, but at least you gave it your best shot.
There are things I miss about the Sutherland, but there are more that I love about the Manley right now and I no longer have regrets switching. It wasn’t an easy swap and took some work, but has been worth it. I did have days when I thought I really messed up and started looking around on USAM, but as I’m sitting here now, things have never sounded better and this Chinook is really revealing herself. Good luck and hope you end up in a similar place.
BTW, I like your taste in music!. I was listening to Reggatta De Blanc the other night and heard things on Walking On The Moon I’d never heard before. During the outro starting with the part with the echo effect on the hi-hat, there is a sound almost like helicopter rotor blades that increases, while turning liquid and then suddenly cuts off, to repeat. I’ve listened to that album since it came out and never heard that before! Also, a big fan of Tool.
