My phono is an AT-LP120 USB with an AT-120E cartridge wearing an AT125LC microline stylus, and I also use a record weight. This phono with those changes sounded really good using its internal pre-amp, or so I thought. But then I noticed certain selections of certain albums had piano notes that 'clanked' in my ears and high notes occasionally gave my ears the sensation of fingernails scraping a blackboard, and the sounds from my sub woofer lacked authority, making soft foomf foomf noises.
So I bought a Pro-Ject Phono Box S (not the Tube Box). That pre-amp fixed the piano notes and separation problems and drastically reduced the fingernail/blackboard sounds, and it did improve the sub woofer. It was a marked improvement over the phono's built-in pre-amp, but I still wasn't fully satisfied.
Enter the Pro-Ject Tube Box S: This is everything I could hope for! All the sonic problems I mentioned are completely gone. Everything sounds smooth and wonderful,...
This was very expensive, but it can be adjusted for a variaty of cartridges which is a must. The sound is somewhat cold, but then again, the tubes are new and probably need to be burned in. Ask me agin in 6 months....
