There are two Rotel RB-1590's listed with different numbers, one shows 100 SINAD and 640 watts while the other shows 91 SINAD and 805 watts. Are those different amplifiers, maybe one is newer but has the same model?
As I said before, many times the same amplifier measured in different places measure different, and I will keep the highest one.

I am working on an online spreadsheet with links to everything so people can check for themselves.

The latter is below
I wish we had hint6 measured in the same lab.
according to Parasound's product and sales specialist from hint6 review in stereophile: "New changes from the original Halo Integrated include a Burr-Brown, analog resistor-ladder volume control; dimmable front-panel volume display; updated uPnP USB receiver; an additional optical input (two total); ball-bearing–supported, solid-aluminum volume knob; programmable default volume setting; 'favorite volume memory' with remote-control button; increased phono-stage gain of 7dB (from 35dB to 42dB) for lower-output MM cartridges; improved left/right channel separation and balance tracking; and updated cosmetics with subtle gold highlights" so not much suggesting it should measure significantly better if at all

I measured the DAC portion to have a SINAD of 101. Its amplifier is much lower:

Here is another measurement of the M10 with distortion (THD+N) about 0.0018% = SINAD 95, blue sector now. Go figure.

Ok I have migrated the data to a Google spreadsheet, let me know what you think.
227 amps now, phew!

Perfect. It's working now.

Here's how to create a quick sort filter, for anyone interested:
1. Select the values from A1 to F228 (the last current value cell)(this will change as the spreadsheet gets updated)
2. Go to Data, Filter Views, Create a new temporary filter view

3. Notice that the table will now have little dropmarks besides the column headers, indicating that you can filter
4. As an example, I selected "Price", then "Sort A-Z" (which is lowest price to highest)

Here's the final result:

As you can see, the table is now sorted by price.
Keep in mind that this filter that I've just created is ONLY visible to me, and is not changed on the original document, meaning, if I close the document, it will revert back to normal sorting, as the owner intended.

I hope this helps! :D

I still have some work to (re)do going through all the magazines and citing the source in the blanks....

Nice work!
Quick thoughts:
- Prices are listed in USD, but European convention is used, which will confuse anyone in US. Price of 7.000 means $7 dollars to North Americans. I know what this means, will everybody else?
- Showing full links looks sort of *messy* IMO. You can easily write stereophile.com as the name, and link the full link as a hyperlink. This will clean up the spreadsheet a lot.
- Are these prices MSRP? or current prices (which are usually lower than MSRP)? or a combination of both. (@ MZKM used MSRP prices to avoid confusion in his speaker spreadsheet).

Prices were given by the fellow user who searched and typed in his spreadsheet before. I don't know his criteria to convert prices.

Agree that the full link is a sore to the eye. I have no idea how to convert it to be pretty, but I insist the complete link is there so that people can double-check for themselves. Any ideas, anyone?

It's easy to convert...just select the value you need to change, then press CTRL+K on keyboard (or right-click and 'Edit Link') and where it says "Text" type in stereophile.com. Done.

Before:

After:
1601669417146.png

Now the link will change to be:
1601669452588.png

Which still links to the correct place.

See entry #23 for explanation of original sheet. Compiled prices on a bored Saturday as stuck at home due to a weekend warrior issue. Listing of prices is an artifact of converting from Excel, as in my original sheet, I used the US/Canadian/British(?) convention of $x,xxx not the European. Was done for fun, not as an exhaustive exercise. Just wanted a rough idea of the Cost of Power.

I adjusted the price of EVAL-1 to include cables and the Hypex SMPS1200A400 power supply. Still it is a bare ones kit, no chassis, no connectors, etc, so kind of unrealistic, but still, it is comparable to barebones amp boards from Hypex, ICEpower and Pascal.

Lot of $5K, $10K amps way down at the bottom with awful numbers. Amazing to see the $6,700 Bryston 4B3 making much less power than the $600 XLS 2502 with similar SINAD
4B3 has been redeemed with another measurements with higher SINAD, so it was promoted to blue zone.

That the same product can be measured by different people and get different results has me wondering: can we track which measurement came from which source and look for patterns?

I have added the source of each measurement on the table now. It is the best measurement I could find. You can try googling a model to check for other measurements. Or if you find a better one than the one listed in the table, let me know and I will update it.

As for which source is regularly better measuring than the other, I cannot guess who and even less why.

I was never suggesting you should do anything different or more. I was just thinking out loud. I haven’t had time to scour the doc yet.
