Why I chose NuPrime and STA-9 ?

– By CharlesKu, audiocircle.com

I would like to share you my experience. I had order OPPO sonica DAC as my audio player. What I should do is to convert my CD to digital files and save it as a *.wav files in USB. Then I can play it via OPPO sonica DAC. My speaker is KEF LS50. I choose a pair of STA-9 as my power amp to ended up my system. This is because when I wish to purchase ST10 I found that there are no DEMO of ST10 amp but STA-9 amp.

It sound good and I decided to purchase a pair of it. I search the internet where I could buy it with my credit card with zero interest for 24 months. I found that there are many, like YAHOO mall, ET mall, u-mall, MOMO mall in Taiwan. Why I choose Nuprime product? This is because I had read the review from web site of u-audio. http://review.u-audio.com.tw/reviewdetail.asp?reviewid=1220, http://review.u-audio.com.tw/reviewdetail.asp?reviewid=1258. And then I found that there is a forum here.  I like the NuPrime of its good sound and has a forum here to discuss and share our experience. I am a newbie and younger audiophile, too. Before I end at my system with NuPrime, I had consider the DIY brand of Breeze audio C20 as player and DAC (a digital player come with ES9018K2M of DAC with a bluetooth 4.2), SMSL SA-98E (160w*2, Class D power amp) as power amp. These set of system is good sound for me when I listen it at other place. So, I decided to set a system (a combo of player with good DAC and power amp) which may come with better sound. I also consider the set of OPPO UDP 205 with Integra DTA 70.1 or NuPrime MCH-K38. I give up due to it may cost me a lot of money.

Choosing stereo speakers over sound bar

– By kaka89, audiocircle.com

I’m very new to this hobby, and when I was first started I was actually trying to decide between sound bar and stereo speakers. I didn’t know the sound quality difference was so huge.

Soon I realize I need a two channel setup that allows me to stream music from Spotify. However I found it very difficult to find a good Hi-Fi system that supports Spotify natively. So I purchased a Teac integrated amp with AirPlay capability with KEF Q300.

I have been researching stereo knowledge since then. I have read almost all the thread in this forum. And one most important finding is that I actually don’t need Spotify and AirPlay support built in, these features can be provided by Raspberry Pi and Volumio. What I really need is a good USB DAC. This finding opened a whole lot more new options to me.

9 months later I upgraded my speaker to a floor stand Focal Aria 926, and I need a new amp to power these speakers. I choose NuPrime STA-9 and DAC-9.

This setup works as expected so far. I also use Toslink for TV.

Wanted more than what an all-in-one-box would provide.

– By SFDude, audiocircle.com

In this market of multiple choices, I wanted to build a system that was more than what an all-in-one-box would provide. I wasn’t looking for something that was a plug-and-play, download an app, and tie-me-down to a subscription model for streaming services system. (A Sonos system would have been fine for that.) I also didn’t want to spend $2K for each separate component, which would have been made up of an Amp, a Preamp and a DAC.

As I was researching for different components and manufacturers, NuPrime sort of stood out with the DAC-10 initially. This was a preamp and DSD DAC in one unit. I wouldn’t have to worry about separates as long as both the preamp and the DAC portions of this unit were top-notch. Reading reviews online, anecdotal feedback on forums and with the experience of the company that NuPrime was formed from (which is Nuforce), I didn’t have to worry so much about a new upstart that was looking to break into the market. There is a flexibility if I wanted to use just the preamp portion or the DAC portion of the DAC-10 which also appealed to me, should I be upgrading one or the other.

I then decided to go all-in with picking up a pair of STA-9 amplifiers due to the speakers I had chosen, as the recommendation from the speaker manufacturer was that digital amplification worked well with them. This was an easier point of entry due to the pricing of a pair of the NuPrime amps (each was $650 USD). You could say for the price of a single amp, I was getting a solid bargain in having a true pair of monoblock amps with enough power on-hand to drive any speaker well.

In the end, what I really wanted was something that didn’t date me and give an image of someone who is still hanging onto how audiophile components from the “golden” years look. Three NuPrime components had the same footprint of almost one full-sized audiophile component, with all the modern technology advancements of digital amplification and signal processing. They would look equally at home in Stereophile magazine pictures as they do in Dwell magazine photoshoots. And the gear would still sound pretty darn good regardless of their aesthetics.

Great, it looks nice and all. How does it all sound? Effortless. Nothing is really forced in the music. It sounds coherent, powerful but with a restraint that comes with the volume turned down. I have fleeting moments at home when I can crank the music and, when playing good source material, it is really dynamic and engaging. This isn’t the case with the bulk of my source material but for those rare special tracks which are recorded really well, my system lets it loose. For this amount of $$, the two STA-9 amps has enough ‘cojones’ to cajole your passiveness into toe-tapping movement. On really good source material.

On bad material, it is a combination of the speakers and gear that makes it feel flat overall, despite the loudness. I think most of digitally streamed sources, except for some rare tracks, are like that. I really need a transport/CD player and dig out my old library of stellar, goosebump inducing CDs to test this out further, though.

This still doesn’t beat the ability of the NuPrime gear to recreate that toe-tapping magic, though. And that’s what really matters at the end, isn’t it?
