Are you sure about that? It doesn't look like a statement that has much value at ASR.that is, it won't work. It hasn't even been checked whether this device plays music.
but are you asking me about non-alcoholic beer, is it still beer, or about green coffee?Are you sure about that? It doesn't look like a statement that has much value at ASR.
So you're saying it won't work, it can't play music? Really?but are you asking me about non-alcoholic beer, is it still beer, or about green coffee?
yes, I'm half serious, the device has a specific function, if it doesn't do it, it's broken electronic waste and should be returned.
I love ASR for posts like yours.
It won't work to tell a woman to calm down, she probably won't calm down, she'll probably get even angrier. B200 if it gives a signal to the analyzer and signal not broken, then you know it's working.So you're saying it won't work, it can't play music? Really?
I'm just bemused by posts like yours.
B200 by itself will do nothing except amplify.
yes, you are rightThat is the only function that an amplifier has. You have given the B200 a very high compliment ... although, I suspect, unintentionally.![]()
Nope. They are simply different animals. One is an integrated amp (pre+power) and the other is just a power amp. Pretty common. What is the problem?LA90/D is a standalone unit,
B200 is not a standalone unit,
The problem is that we don't have a preamplifier and in my opinion this has an impact on what and with what current, gain we connect - am I wrong?Nope. They are simply different animals. One is an integrated amp (pre+power) and the other is just a power amp. Pretty common. What is the problem?
Furthermore, the scale is logarithmic, 150W is approximately 1/3 of the distance between 100W and 200W
how it performs in terms of heat generation.
Another report from the living room rather than from the ivory towers. Fairly loud listening over 2hrs 27w measured by the smart socket (per B200). The amps are cool to the touch. Even the A70 Pro and D70 Pro Sabre got a bit warmer in comparison.
You may want to see it the other way around, with a (combined on spectrum) line-level nicely recorded music signal right before the amp.I know I probably need more data, but the 5W gain at which the measurements are taken corresponds to what volume level, average, 36dB or 11,5dB?

on the other hand, if I read these graphs correctly, even at 145W there is still no tragedy and no significant difference? (5W vs 145W)

Why?Well, every power amp needs a pre.
Okay. Almost every home audio power amp needs a pre.Why?
There are professional audio interfaces with Analog volume control and enough output voltage to drive this amp into clipping if you want.
But what are you looking for ? What you write is true for any power amp. Amir measures a product on its own, for this amp like for any other device he has tested. Measure a full system is quite a different story. What do you mean by a whole system ? Should he measure as a whole the preamp, and also the Dac before the preamp, and why not the speakers after the power amp ? Your claim has has no ending and sounds a non sense. People rarely buy a whole system in one time.The problem is that we don't have a preamplifier and in my opinion this has an impact on what and with what current, gain we connect - am I wrong?
Maybe I don't know all the manufacturers, but it seems to me that the vast majority of those who decide to introduce mono power amplifiers to their offer create a dedicated preamplifier for them and so it should be considered as a whole.Topping is no exception to this rule (Pre90). It seems to me that the design phase includes these separated devices as a whole. People of course mix and change them later, but I think most lose measurable control over it and are only guided by what they hear, and they don't really know whether there is any overdrive or clipping.

By the way, topping manufactures good preamps and DAC/heasphone/line/preamps. You just have to go to their reviews on ASR.
