As Vox/bass in my band I write 99% of my lyrics. I have great difficulty reciting any line of my own hand without hearing or playing the bit of music it's supposed to go to.
Just 20-odd posts saying 'no, don't'.
Your reasoning seems flawed. The cold may contract the windings enough for frost to settle in between and even reach the core. Once out of the fridge the aging process will most likely be accelerated if the string hasn't gone brittle already.
Discogs is usually the place to go for vinyl, it's where collectors gather and knowledge amasses. Not sure if they have a section for 78s but it's the best spot to start.
Try the beyerdynamic dt880, comparable to the dt770 but open backed. If a bit of sound leaking out is not a problem (recording or traveling) they are nicer to hear and more comfortable than the dt770.
If for studio use on a budget you can't beat the Samson sr850 on quality for money. Nearly every professional studio in the world will have some of these.
Little Big are scoring high on innovative videos. Most of their modern stuff are real eye catchers. Story driven stuff like Rock-paper-scissors, Hypnodancer, even Faradenza, to plain weird Go Bananas, Uno and Tacos. Well worth a watch!
Ministry and White Zombie. Their early 80s effort respectively being electro/wave and scratchy wannabe punk.
Ministry found their feet somewhere between Twitch and Land of Rape and Honey.
