2016年3月15日 · A push-pull class A amp has full current flowing all the time and is at best 50% efficient. A class AB amplifier reduces the current by only supplying current as needed to drive the load with minimal standing (constant) current just to cover the “gap” when the signal transitions from top and bottom devices.

2022年4月17日 · This is a review and detailed measurements of the AIYIMA A07 desktop amplifier based on TPA3255 class D amplifier chip. It was kindly purchased new by a member and drop shipped to me. The cost is US $72 on Amazon including prime shipping. And as of this shipping, it also included a 32 volt, 5...

2023年10月12日 · I need some recommendations for a class D amp for my Martin Logan EFX electrostatic speakers. I found impedence charts of the ML electrostats, and they begin to dip starting at 1kHz. At 3kHz, they are at 4 ohm, and at 10kHz, they are ~1.8 ohm, and at 20kHz they are less than 1 ohm. ML...

2018年8月30日 · Some Class D amps I've seen are functionally "in-between" a dedicated power amp and an Integrated Amplifier, in that SOME have tone controls or have multiple input types (RCA jack, 1/8" jack etc.) but not any ability to switch between distinct source inputs. The user lacks the ability to have multiple sources connected, and being able to ...

2021年1月20日 · Plenty of class AB amps have inaudible distortion and noise levels, and using switching (class G) or tracking (class H) power rails with an A/AB amp allows them to approach the efficiency of a class D amp. It should also be noted that class D is most efficient at maximum power; at low power levels it is much lower, though still very good.

2020年9月13日 · Get an affordable, pretty, well-built class D power amp from any of the small guys (with proven build quality rather than obvious mistakes like some dissected on ASR), and then some pretty boutique preamp to go with it. The Benchmark AHB2 is of course another option, but IMO it looks hideous.

2019年11月17日 · Covid pandemic forced me to work from home so I need a small amplifier for a desktop setup. I'm looking for a well measuring class D amp with no frills: analog in, speakers out, volume pot & power button. 100-150€ max. Any recommendation?

2023年2月4日 · This is a review and detailed measurements of the Hypex Nilai500DIY class D amplifier module with PS500DIY power supply. Parts were provided by the company and member @Rick Sykora was kind enough to assemble it: As indicated, the single channel amplifier is on the left and the power supply on...

2020年7月21日 · Starting to look at for a new dac/preamp combo that will feed into my class D power amp. A good remote is essential. Shortlist so far is the RME ADI-2 Topping E30 Topping DX7 pro SMSL M400 Schiit Modi 3 (and continue using the pre on my integrated amp) Which would you pick as a good match for...

2021年2月6日 · New to the fora and trying to find out if any of the Class D amp manufacturers have succeded so far. Read the less than fantastic review of the XTZ EDGE 300, one i had hopes for. I am also trying to find out regarding the Nuprime MCX, very little information there. Does anyone have any info/measurements regarding these amps.
