Topping’s new amplifier - Mini300

[Guddu]

Looks like PA5/PA5-II has got re-birth as new MINI300

 

[Bleib]

Nicer look but I hoped some technology would come from TP RA3

 

[Fletcher Munson]

Any specs or info at all ?

 

[Bleib]

Similar size so I don't expect much difference

 

[BeeKay]

Cannot find any info apart from this thread. Where is it from?

Not yet

 

[Fletcher Munson]

I'm not going to buy now cos i'm annoyed they release teasers with no info

 

[Bleib]

"It will be released on Nov 4th, stay tuned, thank you"
So. it's a quick release

Thank you

Very affordable

I hope the Topping Audio Mini 300 amplifier is reliable for early adopters. It appears to be a great value.

 

[Jcrow]

Looks pretty good. I'd been holding out for topping to update their small amps because I didn't like the plexiglass look. If they update the B100s in this style, I'd be down.

Specs seems to be identical to the ones of a PA 5 II. I am wondering if there are any pros/cons to it?

 

[perceptionist]

Will there be Mini 300 Plus or Mini 500?

 

[Matias]

Looks similar to what they already had... What is the point?

Topping already has excellent R&D to develop top measuring discrete DAC and discrete opamp stages. I want to see them using their talents to develop top measuring discrete class D amp topology and feedback loop, no chip amps, and bring some legitimate competition to Purifi, Hypex and ICEpower on high power amplifiers.

My speculation is the point of the Topping Audio Mini 300 is to offer the performance of the PA5 II for a list price of $139 and without the nomenclature of 'PA', so as to avoid association with the PA5 amplifier.

EDIT

The decline in price of the original $349 'PA5' to the $219 (when measured by Amir) 'PA5 II' to the $139 price of the Mini 300 reminds me of recent stories talking about the 'involution' of parts of the economy of China - a race to the bottom spurred by excessive competition:
