12au7 rolling - Radiotechnique v Mullard v ?
After much tweaking, I’m fairly pleased with my system which includes a tube preamp w/solid state amp (100% Class A). The tube preamp (Response Audio Bellamax) with two La Radiotechniques 12AU7/WA (6189) offers great tone, dynamics, resolution and a tight bass. I’m wondering if it’s possible to preserve those traits and add a bit more body to the vocals. I’m considering purchasing Mullard M8136’s or CV4003’s but I’m wondering if the bass will become bloated or lose dyanamics. Has anybody compared Radiotechiques (14mm plate) with the Mullards?
