“The sound of the Tube-Tech HLT 2A is sensational! True enough, Eddie Van Halen nailed it when he said, ‘You can’t polish shit’, but any source with the slightest whiff of quality will sound better than before when processed through this machine…What I’ve accomplished here with two or three dB’s change, leaves me in grave doubt about the EQ’s that used to be my favorites…Whether or not I need the TUBE-TECH HLT 2A is no longer a question, because the sound is simply grandiose. The only issue is the necessary petty cash. So, off to the bank…”

“The HLT2A delivers what it promises in a smooth, coherent and unfussy manner. Other tools are available for fussing and fiddling.

This is a Rolls Royce of EQ’s: an elegant solution for smoothly tilting things to suit the context and I’d love to have this in my recording chain all the time”

– George Shilling, Resoution Magazine


Conclusion from the review:

“Except for cases of “frequency surgery” where you need to delete a pinpointed frequency without collateral damage, the HLT 2A is extremely versatile.

In the mix, it can remedy a poor decision by retrieving voice presence and brightness without aggression. Thanks to the magical TUBE-TECH tube electronics, the vocal easily finds its place in the mix and truly blossoms in a way even the official plugins validated by the brand can only approximate.”


“If you want to experience valve performance at the highest level in a microphone preamplifier, then the TUBE-TECH MP2A is one of the best ways that I can think of to do that.”
