Pro-ject speedbox: Is improvement worth the $ ?

The Speed Box offers a feature set that would lower the noise floor, improve resolution, and increase dynamic range: The Speed Box sends the AC input through a regulated and shielded component isolated from the turntable chassis. The AC power supply is off-chassis as well. Add in quartz-regulated speed control and that's a lot of functionality for $129.

Of course the soundstage would be deeper and more delineated, and the bass deeper. Those are the kinds of improvements you get when you keep AC artifacts out of the signal chain and thereby lower the noise floor. It's especially critical on turntables, where the cartridge's job is to amplify vibration. Keep the vibrations you don't want off the main chassis. That's what the Speed Box does.

However it does it the SpeedBox IS da'bomb .

Sorry for the late response. I've been away for a few days.
Kiko65, I purchased the Graham Slee Era Gold mkV. I also purchased a Ortofon 2m Blue brand new but haven't received it yet. About a month ago I decided to get into vinyl for the first time. Since then I've been researching tables, cartridges, accessories, etc. I haven't spun one record yet and already I'm getting the upgrade bug. Started with a budget of less than $500. Today I almost bought a used table that retails for $1,600 new. Oh god.

The ExactPower is a waveform correction system. It actively removes high frequency irregularities from the waveform; it does not filter them. The work is accomplished by a high efficiency, pulse width modulated power amplifier.

Will a speedbox be an improvement? Don't know. Only one way to find out...

Yes it is worth the money

I thought I was bad. lol. If you haven't even listened to a record yet, you need to stop spending. Get just what you need to play some records and do some listening. The only problem with upgrading now is that you don't know if you're really upgrading. Vinyl is no different than anything else. There's plenty of good stuff out there, but you won't like it all. Just like with speakers and electronics. One thing you'll definitely need to keep in mind, is that if you bought new cartridges, they break in. A lot. More than any other component. Sometimes, new carts sound so bad, you may think its defective. Put at least 50 hours on it before doing any serious listening. 100 is better, but I can tell you won't have the patience to wait that long.
