Croft Micro 25R Line & Phono Preamp
A Worthy UpgradeThe Croft Micro 25R takes a brilliant design and makes it better. Based off the classic Micro 25 platform, this version throws in tube regulation to the power supply to give it more control. The difference is striking, both in terms of extension and depth. We've connected this preamp to different amplifiers here - both tube and solid state - with great success. It goes without saying, though, that there is tremendous synergy with the Series 7 and 7R.
