"I talked to Dirk Brauner and he told me the new Valvet X is what the Phantera is to the Phantom and what the VMX is to the VM1.
So it's a little more vintage sounding compared to the stock Valvet."
Like the "Phanthera" as the brother of the Phantom with a more vintage like sound, the Valvet-X goes the same way compared to the Valvet. The X has no Phase switch and is only acoustical cardioid which offers additional 3 db in noise to signal ratio. The first test in german magazine Professional Audio had a result of 85.4 dB/a. I mean, thats good
