    Pioneer SA7500 upgrade recommendations

    Hi, A friend gave me a 'faulty' SA7500 to discover that it was actually working. He got it fro ma store telling him it was broken too. Missing jumpers on the back and a broken led light confused both of them thinking that the power supply stage was broken. So it actually works fine, but it has...

    Dual 1257 cartridge replacement

    Hello, I restored a Dual CS 1257, but initially simply bought an OEM ULM-152E replacement stylus ($13) for my ULM-50E cartridge because I was just trying to make sure it worked before spending more cash. Well, it worked (pleasantly well), & my turntable hobby has exploded in the interim. That...

    From KEF Reference Model One to KEF Reference Model 103/4: upgrade or downgrade?

    I currently have a set of KEF Reference Model One and I love them. However, I came accross a pair of Reference Model 103/4 on a local listing website that need internal speaker refoam. The price is accordingly (cheap) so I was wondering if it could be a nice upgrade if I buy then refoam them?

The difference was amazing- my Polks woke up from their slumber and started to sing. And though it's a cliche, I heard...
