I think the measurements look very similar to Amir's results, it's just a matter of different scale and format.

Wouldn't that be closer to 20bits considering: 20bits = 122.16dB 21bits = 128.18dB Cheers, Jake

Nice review, thanks. Could you do these charts with a log scale instead of a linear scale? it seems like that would be more useful.

An order of magnitude is usually 10 times, so that would be 20dB. It's a good engineering rule of thumb if something is an order of magnitude better then something an order of magnitude worse is unlikely to have any effect. E.g. if you wanted to measure an amplifier with THD+N at -60dB, then you...

The Schiit Mani got 4 different gain settings, the overload headroom for a 5mV cartridge is as much as 26dB at the lowest gain setting. So it does have some options to play with and adjust for a better fit with a specific cartridge. The reason the headroom matters is when you have scratches/dirt...

The U-Turn Pluto 2 looks like good value at $99, I hope Amir gets a chance to do a set of measurements on it in the near future. However I'd say the 100pF input capacitance is a bit high, it will make some cartridges sound bright with a rise of a few dB in the high frequencies and also the 9V...

Looks like the cheaper Schiit Mani is a better choice unless of course someone got a very specific need for the digital outputs. It's a bit strange they didn't go all the way and added a USB interface. Anyway, while the performance isn't that impressive, I'd still like to see a...

A DPS corrected on axis frequency response like that is pointless without showing both the horizontal and vertical off axis response +-90degrees.

I think you are confusing snake oil coupling caps with common sense electrolytic caps. There is nothing snake oil about using good quality brand name electrolytic capacitors, ask any repair technician if they prefer cheap chinese caps over quality japanese ones. You already know the answer to...

I don't understand why you're being so defensive, why not see this as an opportunity and start offering modules with upgraded capacitors for a little extra, sounds like an excellent business proposition to me. Then the end user can decide for themselves if they think the cheap caps will be just...

So we can conclude brand capacitors are better than cheap chinese capacitors? and a $2000 amplifier should not try to save $10 on capacitors.

I used to love my Stax back in the 90s, they did sound very open and detailed, but the bass was just not there. It looks like these headphones are very similar in sound.

Ok, assuming you speak the truth, so in your experience are reputable Japanese caps more or less likely to leak than cheap Chinese ones?

I'd have no problem paying $10 extra to have high quality Japanese capacitors in my amplifier instead of questionable Chinese caps, especially when we are talking a $2000 amplifier then it's not even a questions, everyone would go with that option. I've seen plenty of cheap caps leaking after...

That sound like both a bad engineering and marketing decision, please explain how how this decision would in any way benefit the end user,

Sure, but why make a premium product with cheap ass capacitors? Why not spend the extra $10 and get some brand name Japanese high quality capacitors with a known history of lasting decades under high load and temperature.

meh, this is a $2000 mono amplifier, no one needs to prove it's bad, however it need's to prove it will stand the test of time which is questionable with no-name capacitors.

I tested some caps in a piece of hifi equipment from the mid 70s just yesterday, the caps were all nippon chemicon and I was ready to recap the whole thing, but I wanted to do some testing first and found that all the caps measured like new, seriously, the main filter cap 1000uF/25V had an ESR...

This is a $2k+ amplifier, I really do not understand their decision to try save $20 on capacitors when everyone would give a thumbs up if they'd just put in some Nichicon or similar Japanese brand name capacitors instead of cheap Chinese ones.

Let's see some actual measurements of these speakers, most manufacturers wildly exaggerate the efficiency of their speakers, just look at Klipch, they are off by as much as 10dB, that is directly lying to the consumers, surely their own engineers knows this is wrong, but marketing needs this lie...
