2016年2月13日 · This is a review and detailed measurements of the Niles SI-275 stereo power amplifier. It is on kind loan from a member. The SI-275 is discontinued. But since it is sold to the custom integration channel, they come up used and in working orders (companies pull out gear wholesale to redo...

2020年9月19日 · I just reviewed the Niles SI-2150 amplifier. This is a quick teardown of the same. Here is the main entire amplifier in one shot: General construction seems fine. The heart of the system are the two UC250LP-M OEM amplifier modules from Hypex. An input stage allows variable gain (board...

2019年4月26日 · I've had this amp for a few years and it seems overbuilt, but appearances can be deceiving. For all I know it could be an absolute dog on the bench. I did some A/B comparisons, level matched, with a B&K 125.2 and I wasn't able to discern any audible differences. The Niles typically sells for $100-150 used and appears to be well made to say the ...

2020年3月16日 · Sounds just fine! And one other benefit of these amps are the line outs, which I believe companies like Niles and Sonance routinely put on their amps for daisy-chaining. Instant sub out! For old 2.1-channel enthusiasts like me, that's a big plus, because a lot of the older preamps and power...

2020年3月15日 · I just bought a Niles SI-275 and SI-245 from Craigslist today. Both amps have identical PCB's. Just larger output transistors and Transformers. The input signal path is all discrete transistors. The input capacitors are both good grade NP with a 220uF bypassed with a 22uF. My first plan is to use both amps to Bi-amp my Totem Rainmakers to see if I can make them behave better. You can see my ...

2020年9月18日 · Of course audibility is the main concern. How can anyone question that? The goal is reproducing sound with fidelity. Thank you Amirm for the concise, useful review. This product appears to be outstanding value for pragmatists. I wonder if this is the same amp used in the NAD c 368 and c268.

2020年10月26日 · Long story but I've ended up with both the Niles 2150 and the Stageline STA-400D mentioned above as having the same HYPEX units. Both as new, I'm in the UK and they were similar prices. Stagline was £240/$328) and the Niles was £280/$380. Have been auditioning them side by side with a rough non...

2024年1月12日 · Hi - I have a Niles si2100 which is a 100w class D amp, plugged into KEF Q150s in a small/medium sized room. Music is fed by a sonos connect directly to the niles (the connect functions as a preamp and uses its internal DAC). I mostly listen in the 60-70 db range. Will i get better sound by switching to use the Yamaha AS501.
