I've never had a Musical Fidelity but they enjoy a fine & long-standing reputation. I've never had a Fosi amp either; recently they have enjoyed as reputation as a good, cheap amp filling roles where there isn't the highest expectation. I'm liking the Topping B100's but I like a certain type...

No, I've no Fosi. The B100 comes with a 38 VDC / 4 ohm PS which I assume is switching mode; this ASR used to make measurements. I have no reason to suspect it is less optimal however it looks like noise is the biggest contributor to the B100's THD+noise result. So maybe you're thinking of...

Since you ask, the pair of Topping B100's is US$ 600/pair; the price of the current, comparable VTV stereo amp with 1ET-7040SA modules and VTV/.Sparkos buffer is US$ 1750 (per VTV;s website). But note that the ET7040SA module that supersedes the 1ET400A is a bit more powerful than the latter...

My Topping B100 monoblocks have arrived and are working fine. What is obvious is that the detail, clarity, transparency and air are remarkable. However I can't yet say how much better they are than my Purifi 1ET400A amp which is certainly also great in these respects. (Maybe if may aged ears...

The Mao years were a catastrophe for China. First the "Great Leap Forward" that literally killed tens of millions, then the "Cultural Revolution" that killed more and set back science and industry. I know a few Chinese people who will admit the country would have be better of had the...

China is a place of contradiction: some things good, others very bad. The CCP government has certainly raise the standard of living there for most enormously since the end of the Mao era. also in the good side: China is the leader in EV production and intends to dominate the world market, at...

Again, when a maker's out-patent design is copied they have no right to complain. (There is no special argument for audio equipment.) If the don't like it they can come up with a NEW patentable design, (many do just that), OR they can reduce their prices -- those are the options in a free...

The Chinese can build to whatever quality level they want to, OR whatever quality you want them to if you are off-shoring your manufacturing. Needless to say many Chinese makers will decide for cheapness vs. quality. The days are long gone when China was only about cheap labor. Labor there is...

You can believe I've got those same problems. ;) Mocking people for what are obvious typos is ad hominem attack and a fallacy.

As previously explained, one patents expire they are fair game to be copied. Good products are copied everywhere all the time for all sorts of things -- what entitles audiophile equipment to a "special pleading"? What seems to bother many audiophiles, (not you of course, @2FarGone ), is that...

Thank you, JDC, so kind. Believe me, I have pretty thick skin. Different? Me? Maybe; I believe that I'm a middle voice between hardcore objectivists and hardcore subjectivists. I've quit knocking tube sound -- that is, to the extent that I ever did. Tube equipment has qualities that...

Could you not have measured the cap in the other speaker xover? Or did the caps fail in both speakers? My Sonic Frontiers Line 1 preamp is more that 20 years old and Sonic Frontiers is long out of business. However it is still fully serviceable at Parts ConneXion which is owned by Chris...

Sorry, guess I misunderstood you. Yes, class B inherently has crossover distortion due to the non-linear behavior of transistors when driven at near-zero voltage. With true class A amplifiers there is no crossover between "push" & "pull" transistors because the voltage is "biased" so the...

Fosi has a established a pretty good reputation. I'd say for $80 don't sweat it. As for Topping I have TP30 Mk.II which is a desktop DAC+amp; it's about a decade old and has always worked flawlessly. My D90 (AKM version) is 6 years old and likewise has & is working flawlessly.

Crosstalk? They're monoblocks. :cool:
