Hmm, firstly - ears are your auditory sense, not your eyes. Markbass are moderately overpriced, for the drivers they use. Glockenklang are very expensive, but there again they have Volt transducers, handmade in the UK. So, the price is justifiable. I can't honestly say I am overly concerned that you think I may be exaggerating-my-point, I know what I hear. I trust my ears. To me, an experienced sound engineer and bassist, the difference is clear and it is significant.
