Topping Mini 300 Amplifier Review

[Timcognito]

You can try it out first. Some 12-volt triggers also respond to 5 volts.

Alternatively, you could get an inexpensive 5-to-12-volt DC-DC converter from AliExpress.

Or you could get a 5-volt relay board and a small 12-volt switching power supply (really small), connect it to the trigger input, and use the relay board to switch the mains voltage.

Thanks @Roland68. 5V trigger worked flawlessly in the 12v Mini circuit with a little fake out as it came on within 2 seconds but took 20 minutes to turn off. Turns out the Node has a 20 min delay before the turn off trigger. Problem solved.

As a percentage, correct.
I'm talking electricity bill
5W usefull-25W waste .

Do you own any amp that gives you a positive value?

NEW BRZHifi PAD-30 : Dual TPA3255 +PFFB @ $99

Hi amigos Just to share I found this new dual TPA3255 + PFFB. The price seems very attractive. Makes me think the 3E Audio A7 BTW. I wish Amir could test it. See attached filed for details Main spec : PFFB Dual TPA3255 (seems to be a one chip per channel) Trigger Pre-out Upgradable Op Amps...

Unbalanced input only = no go (for me).

I've got my Mini 300 hooked up and running. This is my first Class D amp (also first time running balanced). The rest of system is a Bryston B60 integrated and Topping E70 Velvet.

Quickly noticed heaps of detail, MUCH smoother sound, and spaciousness. Vocals are significantly more realistic. Everything I throw at it sounds live and realistic (I'm likely generalizing Class D here). The bass delivery was more pronounced than the Bryston and needed taming. I run Audiolense + umik-1 as the final step, so I wasn't ready for a good listen until that was setup.

Can't wait for the Topping E50 II DAC review.

Thinking of using E50 II with Mini 300 but E50II has not trigger out.

If this was the only issue that'd be fine with me.

I'm using it with the E50 II, but I use the WiiM Pro as the 12V trigger source. The setup gives me excellent results in terms of both sound and convenience (the E50 II features an auto-standby mode, which is very handy).

Finally received my Mini 300 today, after ordering it back around November 27/28. I'll be setting it up sometime in the next few days.

Will these properly drive the elac dbr62? I currently have an pair of dbr62 driven by the audiophonics nc252mp (2x250W) in my living room. I have another pair of dbr62 in my bedroom waiting for an amp. I was about to pull the trigger on another nc252mp, but these mini 300 are 5 times cheaper.

Looks like minimum impedance is 5 Ohm, so not a particularly difficult load. Not very sensitive tho. It pretty much depends on how loud you will be listening. Distance, size of room etc.
Given the Mini 300 is so cheap, I would be tempted to buy one and see if it has enough power for your needs. If not then upgrade to a bigger amp.

Performance-wise, it's perfectly adequate, in my experience. I can't turn the volume control past 12 o'clock with the DBR62s without it becoming unbearable in a 20 square meter room.

But you have to be careful that the Mini 300 doesn't end up in the living room .

Mini 300 has no sub out.
If E50ii is paired with Mini 300.
Is it safe to do following:
[E50ii]-->TRS-->[Mini 300]-- speaker wires-->[Passive Speakers]
[E50ii]-->RCA-->[Subwoofer]

Yes.

Doing the same thing with an A70 Pro. Works flawlessly.

Just use a single mono RCA cable from E50ii's RCA L (or R) to Subwoofer, right ?

Depends on the sub.

Some may sum L and R inputs internally w/o attenuation, in which case you'd lose 6dB playback volume by connecting just one.

And in rare cases the bass line of a track may be panned to one side, in which case you'd lose that bass line when you connect just the opposite channel.

 

[BeeKay]

Depends on your subwoofer. Mine has L/R inputs.

My subwoofer also has L/R inputs but L is labellled LFE. I connect single mono rca cable from amp's subwoofer out to LFE.
Is this wrong cabling method ?

If I am not mistaken the E50II has L/R RCA out and no sub out. So I would connect E50II L/R to sub L/R
