I'd like to see a Cayin N7 test. I enjoy using my n7. I hear clear differences between other systems when use Monarch mkiii (at least i think). It sounds very pleasant, very detailed. Hence I am wondering what would be the result with amirm's testing methods.

Turntable

The best specs turntable ever produced.

Kenwood KP-1100 or it's counterpart different year different nomenclature KP-9010

I agree with your list. I think there is many of us on this forum that want to see if there is an objective improvement from the likes of the Denon x4800H.

I also wonder whether there is an objective difference between the Marantz AV10/AMP10 and the Denon A1H.

would be interesting to break it down.
IE Phono stages.

Headroom .
The importance of headroom, and implementation by manufacturer to overcome this in their design.

Capacitive loading capabilities of the device, how important is this to performance.
MC resistive loading and quality of devices.
IE: devices should have Azimuth checking capabilities built in.
VTA stylus angle testing capabilities, and its importance to performance.

Basic what matters and what doesn't effect SQ as much.
But then SQ is subjective.

My preference would be fuller lusher with underlying speed and cleanliness.

Microphones. Please measure microphones, here’s why:

Microphones are still surrounded by the same myths that speakers once were:
- Measurements (FR’s) are given only by manufacturers, with unknown amounts of graph smoothing. There are (afaik) no independent reviewers that measure mics.
- Microphones can be extremely expensive, even though the basic materials don’t seem to warrant the prices.
- Microphone characteristics are surrounded with marketing language (“good for bringing out the timbre in tenor voices”, “smooths out harsh transients”), even though all of this behaviour could and should be explained by Frequency Responses and Distortion.
- Microphones are a fundamental part of the Circle of Confusion.

But how to measure mics?

The cool way is to invert the Klippel: mount a “perfect” white noise generator on the place where the mic is, and then spin around the mic to see what it pics up on every angle and distance. But I suppose you can’t mount Revel Salon 2’s to the Klippel and swing them around so it must be something else.

A static measurement straight from the main intended angle could work, although directivity (polar pattern) of a mic is a core feature.

I know it’s not for this forums users, but I do think it deserves attention.

Maybe it exists somewhere, but googling on Microphone Measurements only shows me Measurement Microphones…

On the Android side there is known variation in sensitivity and frequency response between phone models. SPL meters will suffer from this, so an app may perform well on one phone model and badly on another. It's the same root cause as Wiim's room correction performing well with some phones' internal mic and poorly on others, and why they added external USB mic support for things like the UMIK-1. Apple have put effort into making sure the mic performance is consistent on all iPhone models, so SPL apps should perform well there.

So you could use an iPhone to check the accuracy of your android phone.

This looks interesting. Powerline networking for IP audio, supporting Atmos.

@amirm
Sorry to draw your attention to my post, but I’m really curious to your opinion on this.

In summary: If transducers (speakers and microphones) are the least accurate parts of the signal chain, then in order to break the cycle of confusion, shouldn’t be microphones the next big subject to be measured? Not saying ASR should do it, but talking in general.

RSL IA255 amp. Surprised it hasnt been tested already... a $110 amp with HPF and no load dependency? It's perfect
