I have measured the distortion in many resistors and the Susumu metal film resistors are the best.
Interesting how tastes differ. I actually prefer the design of the Vera, and by a pretty large margin.I tend to agree, we are in the same price class, and power class here with the NAD M23 which uses the higher end Purifi modules and an industrial design on an other level. It makes this a hard sell.
I can see your argument. It is not easy to reach back and remember where the gain and bridge knobs are. On the other hand, we see the gain switches as an installation "set and forget" feature much as the bridged knob.I looked, read, looked again, I was about to give up that, shame, there is nothing I can criticize, the horror!
Then I found it!
I don't like a major set-up setting like stereo/bridged to be treated the same as operational settings like gain and that they are placed next to each other. You use the bridge switch once the amplifier is connected but you adjust the gain controls later on. It is entirely possible to change the amplifier mode by mistake if you are trying to adjust the level controls standing in front of the amplifier but reaching the knobs at the back.

It would have been perfect if the bridge switch would be made different and difficult to be used by mistake. A slider switch with a recessed tag is the best for such settings. Example below.

Needless to say. I am nit picking. I voted Great. However, excellence is not easy to achieve.
I know it is very personal, but to me, that power button in that position in 2022 screams DIY. Don't kill me, i repeat, personal taste.
Out of curiosity, where does this preference, and/or the opinion come from - that having no front power control = superior industrial design? Other than minimalist aesthetic, why is an accessible power control on an amplifier bad? Genuinely interested in answers from anyone with an opinion. Thanks!I tend to agree, we are in the same price class, and power class here with the NAD M23 which uses the higher end Purifi modules and an industrial design on an other level.

The test I did was not very scientific. I just tested different types by soldering them on the PCB in our buffer and measure distortion with an Audio Analyzer. (R&S UPV). The test was done with a somewhat high voltage of 10V RMS to better resolve the temperature coefficient.Did you make a measurement report and is that available ?
How did you measure resistor distortion and in what magnitude were the differences ?
It is truly refreshing to see an audio component manufacturer respond to a difference of opinion in such a polite and articulate manner.I can see your argument.
I personally was referring to this particular model of button that you see very often in diy amps and about the position i was referring to the center of the fascia, also very typical diy. Again, personal taste, this amp seems to be anything but diyOut of curiosity, where does this preference, and/or the opinion come from - that having no front power control = superior industrial design?

Are we going to talk about this? Edit : @restorer-john did.

Thanks, @biglebowski
You should get this.The test I did was not very scientific. I just tested different types by soldering them on the PCB in our buffer and measure distortion with an Audio Analyzer. (R&S UPV). The test was done with a somewhat high voltage of 10V RMS to better resolve the temperature coefficient.
My initial though was that the larger MELF resistors were superior, but the small 0805 Susumu resistors in the somewhat expensive RG series are really good
Here is the difference between Susumu RG2012P-2490-B-T5 125mW 0,1% with a temp. Co. of 25 PPM/C and a Vishay 250mW 0.1% MELF resistor. As ecpected it is in the low frequencies the differences show up.

Thank you for the reply. Very much appreciated. I have not noticed that gain was also switched. My note would be valid if they were potentiometers.I can see your argument. It is not easy to reach back and remember where the gain and bridge knobs are. On the other hand, we see the gain switches as an installation "set and forget" feature much as the bridged knob.
In addition, there is no harm if you accidentally use the bridge knob while the amp is in use. The only thing that happens when the bridge switch is set to "bridged" is that the right input will be routed to both outputs and you end up with mono sound![]()

Refresher reading: Rules for Review Threads
Basically just personal taste. Molded aluminium with round corners. The two tone aestetics, the finish, the top vents, etc.. About the button, nothing reaally wrong with it, it's just that it's a vastly popular off the shelf button from E switch that we see everywhere from anybody building stuff. That said it's not a bad looking amp.Out of curiosity, where does this preference, and/or the opinion come from - that having no front power control = superior industrial design?

Yes we are! Hoping your wife (and home) have a full recovery.Thanks for another very interesting review, Amir. And all the best to you and your wife. You should know that a lot of us are thinking about you.
Hasn't gain been on the back traditionally? I have an old Heathkit power amp that's 40+ yrs old with variable gain controls on the back.I like the design - but I would still like to have the gain control on the front (same goes for Schiit's tendency to power/gain switchen on the back).
and generally get's in the way of the good. But hey, this is audio we're talking about.I looked, read, looked again, I was about to give up that, shame, there is nothing I can criticize, the horror!
