Topping Mini 300 Amplifier Review

[jmdesignz2]

Still waiting for higher power Topping Monoblocks...400W into 8 ohms / 800w into 4ohms / 1200w into 2 ohms for $999 each

Grabbed one of these for Mechano23 in nearfield. Definitely sound like a good amp, which is to say sounds like nothing.

Gain seems low on these, I've got my motu m4 feeding it, tried RCA and balanced but maxing out the amp and the motu is not really very loud to me.

I actually ordered two, with the intent of using them for active speakers, but will return one as I can't really afford an appropriate DSP unit. I need a low latency unit with balanced ins and robust control and that's basically just the minidsp flex which is wrecked by tariffs. These amps seems good for that as the self noise is basically non-existent.

I do wish the gain was higher, my aiyima A07 amp seems to have it much higher so I can get more volume out of the amp, but it also scares me because the amp is 'hot' signal wise. It also likes to spark if the leads touch, or touch any part of the chassis.

Maybe you should take a look here.
A Raspberry Pi Pico and inexpensive DACs, or a used mini PC with a 6-channel sound card, shouldn't be so expensive that you have to abandon the project.

Yikes!!

But first, Topping should get its problems and failures under control, especially with the B100 series.
A more customer-friendly approach to handling defects would also be desirable.

This setups for makin music so I have to keep latency low, and I need to just be able to process the outputs of my motu m4.

I don't really need the second amp. I kind of complicated things trying to get my own active speakers in this setting. I just put them in the living room where I've already got 8 channels of DSP and put the mechano23 in the studio space. This is better anyway as the speakers now fit the spaces better in terms of size and dispersion.

I haven't seen any power consumption measurements so far.

Per my measurements, the Mini 300 power consumption is a bit better than the 3e Audio A5se (both presumably single TPA3251) at 7W vs. 9W (idle/very low volume), measured at the wall.
My very old Tripath class D amp uses 6W. My class AB amps were in the 18-30W range (idle/low volume).

Will I hear any difference replacing my fosi V3 with this driving a pair of DBR62s?

Most unlikely once volume matched

That also depends on your source and the music you're listening to.
The Mini 300 is just as transparent as the PA5 II or 3E Audio A5.
That might make a small, audible difference compared to the Fosi V3 Stereo, with emphasis on "might." Definitely not a world of difference.

My source is a SMSL SU1 DAC. Music Rock, pop, jazz.

The DAC and speakers are very transparent, so it might be worth considering, as the price difference isn't significant.

Would the Mini 300's power output be sufficient for you?
If the speakers are on your desk, then certainly, and in a small room as well.
But in a large room with a distance of 3 meters or more to the speakers, you'd have to test it.
What kind of power supply do you have with the V3, and how high do you turn the volume knob?

I have the Mini 300 running my Dad's old SpeakerLab speakers, (2 way 8" bookshelf speakers 1979), in a 3 1/2 bay garage/shop 40 ft long (74 sq-m) with no problems throughout but will say that is a stretch when playing loud at the end of my shop as the speakers are at one end of the 40 ft. I'm very happy with small size, power, and sound.

Whew what my wife & I would give for that third attached garage!

Mine is a separate building. Probably your wife would like it better as I spend a lot of time in mine.

Just for those who would like some more info on this as I was looking before purchasing

I have been using the E50 Ii and this Mini300 for a set of speakers I built for about 3 weeks now and here’s my thoughts

E50 II - bought it for the looks and it delivered.
Sound is as expected from a good dac and the peq and app are a bonus. Remote is a bit wonky/non intuitive. No 12v trigger which is dumb bc they show it with the mini 300 like they were made for each other.

Mini300 - Was skeptical on power, but I have some DIY 2 way speakers with a pluvia7hd and Dayton tcp (4 inch) and it’s plenty for a 25x10 room. It did start clipping turned to more than 80% while the E50 is in DAC mode and full volume BT input but that’s prob the speakers based on specs. Overall, pleased - but I would be sending back if I didn’t figure out the trigger.
Tip: take a usb and add a 3.5 to the end and it goes into the TV/laptop.
Power on sends the ~5v to the mini which works flawlessly

Why not use the Auto On/Off function on the E50 II? I do, and therefore I do not need any trigger.

I think they mean a trigger from the E50 to turn on the mini-300. And I agree that it should have that feature.

Hi, I already bought the E50 II and the PA5 II with balanced cables. Am I missing out on much with this new Mini 300?
