LOL, never in a million will i turn up the volume enough to use 250watts, not on any speaker. My only issue will be my LDR volume control which does not go down quiet enough for late night chatting with background music playing, If I get the new speakers I might have to re think my pre even though its a passive buffer.250 watts into 98dB efficient speakers? Get your earplugs out. Protect your hearing.
Without fft size, this graph doesn't show anything about the noise
Thanks for pointing this out John, your input is greatly appreciated but all this tells me is orchard audio has an amplifier that would work well on high sensitivity speakers, we cant apply this globally to all SS amps can we? or are you saying we can? Sorry I am missing the relation to my question which asks why the designer has said high wattage amps dont fair well with high sensitivity speakers, showing one amp that would work tells me I should buy this amp?SIY measured the noise in the Orchard (Bosc) amplifier in his review containing the AP plot above, and commented on connection to a ~100dB@1W/M speaker...

Edit: but I realise your are talking to Boxem and not me.
No. Residual noise is also in the 30=40ish uv.@boXem | audio Can you hear the residual on your amplifiers, at close range speakers (tweeters) with no input (not shorted).
No. Residual noise is also in the 30=40ish uv.
To be clear, my comment was not to point out a potential defect of the Orchard amplifier but rather say that in general a fft plot without knowing the fft size do not provide any information about the noise floor.

I am more of a mV guy myself.
Indeed. At the exception of the white noise, which seems to be the only one present on the Orchard.It shows you the noise components (e.g., hum, buzz, idle tones) which tend to be the dominant noise sources.
I'm still trying to figure out how 47uV of noise is significant.

Thanks for that link, taking a look now.There was a similar thread. I like the suggestion in post #3

Or Rick could buy a purifi or hypex amplifier now and experience SOTA performance far soonerThere are amps and there are amps. My B&K amps, which were borderline high-end in the day, do make an audible hiss that I can hear up to about a foot from the tweeter. My speakers have a sensitivity of 91 dB/W/m.
It sounds like you do get something when you add digits to the price.

Yes because I dont see them getting cheap, not even in 15 years!Or Rick could buy a purifi or hypex amplifier now and experience SOTA performance far sooner
