Review: GSA Vitrum 501
Great sound (clear and “modern”), good build, excellent price, Hand-Built.
For the price really none.
The Vitrum 501 is the first microphone preamplifier from GSA AUDIO. It’s a Solid State full hand-built preamp in standard 500 series format.
At first glance the Vitrum501 transmits a great feeling of solidity and I must say that the faceplate is really well done (it should be brushed aluminum, instead of the usual colored iron).
Even the switches (PAD, Phantom and Phase) are well laid out and it transmits a nice feeling of cured product.
Once inserted into the lunchbox I’ve tried to record a voice and an acoustic guitar.
The first thing that I noticed is that with microphones that need more gain, like the dynamic ones, you have to turn the knob for nearly 3/4 and you have to be a little careful because in this position the gain is quite sensitive.
After a while, however, you get used to the sensitivity of the gain and there are no problems.
Moving on to the sound rather I have to say that I was greatly surprised: the sound is rich and linear in low and bright in the range high: reminds me a bit the sound of the Focusrite Isa One, crystal clear and defined.
I found it very suitable for recording acoustic instruments because it is not harsh despite being very detailed. Also on the voice gave me a very good impression, especially if you want to record voices with dynamic ranges and that brilliance at the top which makes them very modern.
Obviously in comparison with tools of the upper range (as Millennia) becomes a little harder and less three-dimensional.
