pro-ject speed box 2 , all they say it is ?

i recently purchased a new pro-ject perspective 2 carbon. so far im really loving it. ive read a few reviews saying the speed box makes a great improvement to the sound of the pro-ject tables , though on paper i dont see how it would. ive got pretty clean power, i dont own any 45,s and i like a less cluttered system. and that little silver box would stick out like a sore thumb. but if a 120.00 gadget really does improve the sound that much ill do it. anybody thats tried it please advise, thanks

I bought one for my MMF-7 and can recommend it. What it does is correct the sine wave of the AC, in turn allowing the motor to run at a more precise speed. The actual effect, that I noticed, is better PRaT. I now have some 45 RPM LPs and not having to move the belt is great.

Hi,
I use the Speedbox mkII with my Thorens TD166mkII very modified the first thing it does at 33 1/3rpm is run the motor with a 44.32Hz sine wave you put the belt on 45rpm pulley, making for less motor noise and my thorens runs about speed prefect with the speedbox you can go wrong only $120.00 go for it.

I've got the Speed Box SE II in a system driving a Pro-ject RM10. In my system it clearly added bass impacted and steadied the tone of piano quite noticeably.

If you don't want the "wavy" sound from your albums especially the slightly warped ones that vary in pitch, get the speed box.. it worksÂ… and as stated above it does really well with quieter parts and piano that you will notice some wavy pitch changes at times, this had pretty much eliminated those physical speed issues..

Actually, a Speed Box will have absolutely no impact on varying pitch due to record warp. That's not the reason to buy one.
