“Just wanted to let you know I did receive the replacement cork 1mm mat you sent and it is of the excellent high quality that I would expect from this brand, it is flawless and very impressive. I wish I had recieved this one from the beginning. I really am impressed with the quality of both mats, but I like the 1mm the best, I am testing it on an inexpensive 1970s BSR record changer I have that has plenty of motor and rumble, and even with just the 1mm mat, the noise is almost gone, that is extremely impressive considering the turntable quality. I collect old turntables and I still enjoy the record changers which I use my lesser quality records with, to provide uninterrupted music, and I have always found the mechanism fascinating. I rebuild them and customize them to optimize their sound, and when properly tuned and lubricated, along with your cork mats, and a quality catridge/stylus, it is amzing the quality of sound you can get from these old units. I dont recommend them for your rare vinyl, but for everyday use they are reliable and sound quite good. I have owned some very high end turntables over the years and I have found that even an inexpensive unit can be made to produce surprisingly good sound with some work. i enjoy the challenge. Please see attached photo of my uncommon BSR automatic turntable with the rare 'umbrella' spindle changer. in this photo I have your new 1mm mat ONLY on top of the aluminum platter, it is hard to see, as it is so thin, but I can only hear a small amount of rumble during the quiet passage between songs and with treble and volume turned up. Very impressed with the mat. Thank you!
