The STA-6 Stereo Amplifier (High End Class A+D Hybrid Design)

I really wasn't wanting to spend $450 on an amplifier that I have never listened to before. Money's a little tight and I was having a hard time figuring out how I was going to find a decent audiophile stereo amp without buying one older than 25 years of age and needing restoration. My brother owns a pair of STA-9's used as mono blocks and are rather impressive. So, I decided with my measly tax return, to purchase an STA-6 and use in stereo mode to power my, dare I say Sony SSCS5 bookshelf speakers. Needless to say, this amp is a keeper. It literally sounds like a big, beefy power amp. Lots of grunt and oomph when needed. It's neither bright nor dull.. It just sounds fantastic! Vocals, both male and female are perfect. Midrange that's as smooth as butter. Soundstage thats huge and deep. Dead silent background. My vinyl has never sounded better. This was one purchase that was worth every penny.

Jason Lim and his NuPrime brand have a history of providing superb customer service and truly excellent gear at remarkably affordable prices. Happily, the STA-6 upholds that tradition in splendid style. Anyone who categorically dismisses Class D amplification owes it to him or herself to audition the STA-6, which seamlessly unites the body, depth and overall 'dimension' of Class A with the articulation, detail and speed of Class D. I'm currently using a single STA-6 in stereo mode to drive a pair of JBL Studio 590's (world-class loudspeakers, by the way) and the resultant experience is one of pure emotional engagement with the music. Bravo, Mr. Lim and NuPrime!
