After a few weeks of searching I found this equalizer at Helios. It's a true parallel-passive designed tube eq and it‘s certainly a looker with its black color and great switches. But how does it perform? Let's get to work.
Both channels are linked and controlled with one set of knobs. The Q's are low on boosting and higher when cutting. This is a very nice feature and works very well. The frequencies are selected with special attention to controllability of the midrange area, and with half an frequency-range overlap to the adjacent bands. It is a truely passive design based on switching a set of inductors and capacitors in and out of circuit - combined with an E88CC (6DJ8) tube-based makeup gain/output stage. The max boost/cut is 10-12db depending on the Q setting.
The g14 does have a certain sound to it, but it's very sterile at the same time. It's very smooth and just sounds amazing. At the prices they are going for at this moment it's a bargain aswell. The only thing it doesn't have is a lpf/hpf cut.But that's just a minor inconvenience. This gyraf g14 is just what I needed and it's not going away for a long time.
