I fail to understand the criticism of Focusrite Platinum gear in these forums.
I suspect that some critics haven't spent the time to test the features or examine the sound closely. Unlike the ART preamp, which works on VCA chips, the Platinum series boasts its own coils at the input stage, and discrete componentry throughout - Class A design.
These are a class A solid state discrete componentry pre-amp. The Voicemaster has been recently superceded by the Voicemaster Pro, but both offer excellent value. Unlike later models, this model does *not* offer the digital output option (optional digital card for SP/DIF output).
I use two Focusrite Trakmasters (same Platinum product series), and they are quiet, clean, with good features and good value per dollar. The compression is subtle yet useable, the EQ is not noisy, the controls are smooth.
The Focusrite gear seems to get pretty good and consistent reviews from very many sources - go to

and see them in print - then decide for yourself.
$100 is a great price on this unit. At $200 you could easily resell it. Check ebay.com for current prices if you are in any doubt.
