Good morning everyone, I received a koetsu urushi tsugaru to test from a friendly dealer who has just collected it from another customer of his. I was very happy and mounted it on a Dynavector 507 mkII. my phono preamp is an allnic h7000v. I tried setting it in all possible ways, as a starting point I set the step up with a ratio of 1/20, and then I started messing around... in particular I concentrated on listening to Mahler's second album, an LP of London with Solti as conductor especially on the 2nd and 3rd movements. But I wasn't able to get a convincing sound. Remarkable mid-high range, but a confusing mid-bass to say the least, the timpani and the bass drum are very intrusive and the double basses lack the necessary articulation as if they were equipped with only one string. obviously with this excessive mid-bass the midrange also suffered. I moved the step up to a ratio of 1/26 and 1/40 but while the mid-bass improved the mid-high hardened to the point of screaming. I switched to another LP "Quintessence" by Bill Evans and with this one too I had the same result in the various tests with a confused and poorly articulated double bass and if I increased the step up, while the mid-bass improved, without being really beautiful, the sax began to become lighter and lose its beauty and body. I stopped everything and rechecked the head assembly, perfect Azimuth weight, 1.85 grams, overhang + 15 mm and body perfectly parallel to the disc. I reassembled my faithful Benz Lps and the Ortofon A 95 and everything was as beautiful and realistic as before. At first glance the Koetsu seems aesthetically perfect, the suspension is good and the cantilever is in order. I'm looking for advice, a highly praised product can't sound so bad... could it be the worn out stylus? Help me
