A wishlist of gear to be reviewed by Amir

[Ingenieur]

Not gear really, but smartphone mic accuracy. Play a sweep on a speaker and plot. Perhaps singular tones, etc.

Curious how accurate when used with an FFT app. I'm sure our host could come up with other tests.

And the RB-1582 MkII

Can't afford to buy or send these at present (probably ever), but I'd be interested to see the measurements for the Mycetias Vulcanians and Wharfedale Lintons.

What about, what I've read is, the biggest selling speaker of all time? Dynaco A25. I have a pair but shipping from Canada is not practical unfortunately.

I have three TC 60's and have thought about sending one but then I think why, what am I or anyone else really going to gain? It'd be interesting to see how they measure but I'd rather sink the money into my current upgrades.

Spica TC-50 loudspeaker 1988 Measurements

Sidebar: 1988 Measurements Anechoic data were available for the review, providing a foundation on which to base the technical analysis. The LF system resonance was noted at 65Hz, with a -6dB free-field response at 48Hz, indicating a desirably slow, well-damped rolloff. In-room, well sited within...

Has @Amiram done a speaker splitter/switcher/selector with volume control?
Besides the popular use cases, these products are good for subjectively reviewing/comparing speakers; if you don’t use the same tracks every time nor have a “reference” speaker to compare to, your subjective opinions hold little weight; and it needs to have volume controls for each output in order to level match them so sensitivity is not a factor when comparing tonal qualities.

Not sure of the products out there but looking for ones that have 5-way binding posts (many are the phoenix connector type) as well as being rated for 4-ohm loads (many state 8ohm minimum) I found this one for <$150 on Amazon:

Also, if Amir or whoever wants to do a multi-speaker comparison trying to emulate Harman’s testing, for ~$200 there is a 5ch one:

Please review more DAP's so I won't get in trouble for buying this.

Never heard of it, but since so many of them have flaws and i don't want to use a cell phone, i'm going to get an old Fiio to add to my Fiio collection.

Pro audio brand Røde just released a tiny versatile USB audio interface called the AI-Micro. Dual analog/mic inputs, headphone output, and digitally connects to Mac, Windows, iOS and Android devices. If this thing measured well, even as a DAC, it would be amazing.

For $90 maybe. But I think between the Apple dongle, the E1DA, and other value players I am not sure how this will compare. Would be interesting to see.

 

[mightycicadalord]

Would love to see the avantone guass 7. looks like their own woofer and what i think is a now disconnected dayton amt or similar design.

Streaky mastering YouTube channel did a subjective review and I thought it was curious he mentioned he turned the hf level up. can't recall the last time I heard a speaker that needed that, its usually down. Might be on the softer side of tonality and that has me interested.
