May 22nd, 2017 - Major thanks to u/hi-fi132 and u/MrRom92 for pointing out an article at Audio Appraisal regarding how a Skywin-built player (GPO Stylo in the article as an example) damages the record grooves with audio samples. Any players that look very similar to exact clones as the FU-700 and R200 are to be avoided due to the reasons as mentioned above! The dynamic compliance of the ATN91 stylus is ~11 cu (at 10Hz), which puts it at the low end of medium-compliance. Like the AT3600L, it is well matched to high-mass arms and the heavier end of medium-mass arms, although the AT91 performed well on the lighter SL1200 arm. Capacitive Load

March 4th, 2017 - Added new introduction and made numerous updates to the list of reasons!! Major thanks to almabes at VinylEngine.com for writing introduction to the guide, fixing errors on the guide and rewritten the reasons to be easily digestable!! Sony (ONLY from the lower-end models, including the PS-LSX100/150/200/250/300) **(Uses Hanpin FU-700/R200 models)** No upgrade options, nor serviceable parts that can be sourced easily other than the stylus and belt.Designed to mimic as close as possible a record cutting head/cutting lathe for highest fidelity & lifespan usually fitted to a precision boron , sapphire , ruby or zirconium ultra light & rigid cantilever Awful wow and flutter. In layman's terms, it's hearing warbling-like effect, "gurgling", or pitch wavering. This is due to the combined effects of a small DC motor run with an inadequate power supply, and servo electronics that do not account for to dynamic stylus drag very well (or at all).

Having spent some time admiring it I opened up a brand new AT91 and proceeded to remove the generator canister. It’s held in place by a single Philips screw at the top and a bonding adhesive. Once removed from the body it is secured into the RigB by the same arrangement using the mounting screw provided. When installed there’s no unwanted movement or play in the assembly. Note that the above assumes a phono-cable capacitance of 125pF for the Technics SL1200 Mk5. This value may be higher (likely) or lower for other turntables. Typically, a value in the range 150-200pF is assumed. Comparison Here are the following brands and models (if applicable for certain brands) to avoid, which are made from the Skywin (which shares the lionshare of "Crosley" clones in the market, Leetac, Hanpin (model FU-700/R200 models), and other OEM factories:Enjoyable and entertaining, but a bit thin and rough sounding and low on details. But for the money it's perfectly Ok, a decent performer for the price. Prices valid in stores (all including VAT) until close of business on 26th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) The included sapphire sylus on many Leetac and Skywin-manufactured players, which has a maximum lifespan of between 65 to 100 hours due to the stylus' softer material than diamond. Yes, you can upgrade to a diamond tipped stylus for increased stylus longevity, but you will still have the exact same problems as described in this list.

December 7th, 2016 - Added a number of brands, such as Art & Sound, DCI (aka Funkyfonic), Winco, and Audionac (both vintage Argentinian brands). Removed "Urban Outfitters" as someone discovered that it's Victrola-branded. Modified the Victrola brand and moved it under the International brands section. Job #3 Position a stylus and transducer above a revolving groove, allow the stylus to follow the grove and faithfully reproduce the vibrations encoded within. The recent RokBlok review videos on YouTube by Techmoan also show that his records were seriously scratched and shredded the record grooves on the "Retro Grooves Volume 1" lathe cut record and the Tears For Fears LP as well.
