Simaudio is a reputable quality brand with a 10 year warranty program. After that it becomes a matter of sound preference at similar price point. I agree with kerrybh about the 390 - pream with integrated DAC and phono stage of high quality and functionality. I own one and run it with a Pass XA25. It is difficult to beat at this price point.
There North Collection is definitely worth a listening test.
An integrated bargain?
TAS Alan Taffel reviewed the Simaudio Moon 641 Integrated Amp in Stereophile:
“…What I heard was disarming. The 641 did an immaculate job a preserving the purity a Sufjan Stevens “Pittsburgh”. Resolution and openness were within spitting distance of my far costlier reference CH Precision l1 integrated amp. Vocal, guitar, and piano timbers were spot on. Further, the tracks emotional thrust was undeniable….”
1) It is not easy to surprise a seasoned reviewer like AT.
2) Sonics close to the 3-4 times more costly CH amp ~ bargain
Will be seeking a demo
