Sorry, i meaned L70.E70 is a DAC A70 is an amp.
A70Pro has different looks, different price, different display compared to L70Sorry, i meaned L70.
In their marketing Topping claims 106dbb for 50mv. 93db is quite a gap from that, what happened?
That would not make sense. 50mv test is all about going very low.Per Topping marketing, that is in low gain... i suspect Amir left it in high gain...
And an extension port.A nicer screen with VU Meter and substantially more power at 10-40Ω (see here)
Another reason for changing L70 with A70pro is if the user need a much higher input impedance as L70 is quite low according to this table (by @Veri ):A70Pro has different looks, different price, different display compared to L70
A70pro has more power (not that the difference matters that much)
Other than display and looks there would be no need to replace an L70 with an A70
And an extension port.
They are releasing too much similar products.
You suspect wrong, it's because of the balanced output + slightly different analyser (APx555B vs APx555) + Topping using a noise amplifier to get a theoretical number >95dB, as is specified in their notes:Per Topping marketing, that is in low gain... i suspect Amir left it in high gain....
That would not make sense. 50mv test is all about going very low.
Yes, it looks like JohnYang found a way to have low noise combined with a higher input R.Another reason for changing L70 with A70pro is if the user need a much higher input impedance as L70 is quite low according to this table (by @Veri ):
2kohm for L70 vs 20kohm for A70pro![]()
Topping L70 Headphone Amp Review
This is a review and detailed measurements of Topping L70 balanced headphone amplifier. It was sent to me by the company and costs US $349. The L70 has the beautiful white segmented display. It is the most visible/high contrast display I have seen on an audio product. Volume control is very...www.audiosciencereview.com
