ENGSTRÖM ERIC POWER AMPLIFIER REVIEW IS COMING


While visiting Marten few months ago, I've listened to the Engström ERIC flagship tube amplifiers. These are cost no object, no-compromise statement power amplifiers by Lars Engström, named after a great Swedish choir conductor. I was affected with the sonic potency and the positive impact still lingers on. It was highly curious experiance as ERIC amps were partnered with the MSB Technology Select DAC and I've could get a great understanding about the synergy and a solid hint what to expect by combining them with my Select DAC.

ERIC (65kg per monoblock) was created from the ground up to drive even the toughest loads and it's truly/fully balanced - transformer-coupled from the input to output. ERIC uses T-100 power tuber from KR Audio. These are the contemporary tube iterations of the iconic 845 valves, that implements oxide cathode rather than tungsten. 6L6GCs were chosen to performing the duties of the driver tubes in the triode connection, with EC8010 (a frame grid tube with high gain and low inner resistance) acting as the gain tubes. There are no capacitors in the signal path except cathode decoupling.


So, yes. I'm highly excited to further, intimately explore these highly impressive and inspiring, heavyweight ultimate tube monoblocks. Stay tuned...
