Ecka, I have owned my Sutherland PhD for a good two years now. The Sutherland PhD IMO does many things well.
Atmasphere of course brings up good points, and I'll agree wholeheartedly, a world class phono stage cannot just be judged by that it does one thing right.
In the course of the past two years, there have been three different Cartridges in my system, a 9-10 year old Benz Micro Glider, which had new life, when the Sutherland was inserted into the system. Then I moved onto the Benz Ruby 3. Of course a better Cartridge, which IMO possessed many similar traits of the Glider, retaining much of that "Benz House Sound", but with some better refinement, and purity of sound.
Then, on a whim, I moved to a new ZYX Airy 3X SB low output Cartridge. Here, was where I finally seen just how well the Sutherland could play, as my pristine LPs took on a CD like quality of dead silence, both from groove silence, and as well, whenever there was the slight tick, or pop on an LP, these were then placed much further in the background versus the other two Benz Cartridges.
There's no doubt about it, that Cartridges as well have a major influence on how a record will sound, and how they handle surface noise, and defects in the groove.
I do believe in general, just like Cartridges, that you usually do get what you pay for, meaning that a $5,000 Phono Stage should outperform a $3,000 one, and usually has a better host of features as well.
Of course, it does too boil down to personal preference Some may try a Manley Steelhead, and come away saying that they didn't like it for whatever personal reasons, and particular likes. Synergy with other quipment is as well very important.
There is one man I know, who is a member here, Sunnyboy1956, who recently sold his Sutherland PhD, and moved onto the Nagra VPS Phono Stage. He uses a Michell Deck, a TriPlanar Arm, and Lyra Skala Cartridge.
Yes, he says the Nagra is an improvement over the Sutherland. Mark
