This is THE GEM in the automatic Dual player family.
I simply love this player and it is dedicated as my Mom's machine. If you love your mom, you know how special that makes it :)
It's sonic performance is on par with the full sized belt drive platter players. It is simply a matter of throwing a better cartridge at it to get practically unlimited upgrades, unless you have a lush budget and then you don't even look at mass market players, either current or former.
Compared to the famous Dual rim drives, the belt drives don't hammer music with the at times annoying harshness I find with them. Instead, they have a more laid back attitude, but deliver rhythm and detail galore, with impact that rocks your mind rather than your ear drums (I get headaches really fast with any equipment that is off in any way) and a richness of orchestration that is hard to believe.
Why the 1237?
It is the the peak of automatic Dual design, all the parts are dimensioned properly, everything is balanced and the machine is extremely reliable.
There is a little plastic cap on the arm control pin in the chassis that tends to wear after 20 years, but they are still available new from Germany, or a long lasting emergency replacement can be manually built up with tissue paper and super-glue, effectively making for a reinforced acrylic control cap (look for the Dual Steuerpimpel)
The best part is the arm!
I once had a totally heat warped Eurythmics record.
Would I Lie To You simply threw all tone arms on all other players.
Except the Dual 1237's arm with a Shure/Realistic series cart with an R3X stylus set to track at 3 grams. Watching this arm getting ripped sideways at every rotation and staying in the groove, while still sounding just great, was simply unbelievable!
This player can be had for a song, sounds as fine as a 1249 or 510 or 1242 or 1229 (I have or had them and then some), and definitely better than a Dual with ULM arm and their propietary Ortofon carts.
One of my 1237 chassis (I have a stash in storage as backups, but will likely never need them!) is currently mounted with an AT12 with a Shibata needle in a vintage Sony compact system (not the plastic type, but the wood panel type) and serves as Momsy's system, who couldn't be happier about getting 100% reliable record pampering performance at the flick of a lever.
I visit her just to listen to it ;)
Are there better players?
But first, your ear needs to detect the difference, and second, your budget will be stretched far more, potentially into the thousands these days!
Try it with an old cart body and a Jico SAS stylus. It'll blow your socks off.
