Just installed the latest KR Preamp last night, the P 135. As someone familiar with the Lampi sound (my brother uses a GG) I can say it will surely float the boat of anybody that loves true triode sound. Since the KR 45 tubes are brand new and require a lot more hours of run in time before I can make a full assessment, Keith was kind enough to drop of some NOS Sylvania 45s. It was with the latter that I assessed the circuit's performance. Incredibly fast, full and layered while remaining very fluid. The tone is magically pure. It transformed the system whose amps are the baby Kronzilla KT120 amps. I will bring up the big daddy DX MkIIs shortly. I will also try rolling with a pair of RCA 45s and a pair of Cunninghams. Those looking to take their KR amps to the next level should absolutely try this very affordable (relatively
) little wonder pre. I am keeping this unit for myself and have ordered more. The caveat is that the output V is 1.5. For those with power amps whose input sensitivity requires more than this to reach full potential, I strongly, strongly recommend an in home audition first.
