That appears to be the case.In other words, does it mean that the LA90 Discrete has been completely reborn as a discrete circuit product?

The new one is 100$ cheaper (MSRP) than the old model, so it's net 200$ difference.Does anyone know the reasoning behind it? Torn between selling my LA90 and getting 2 discretes or getting an extra LA90 for $300 off on clearance
DF = speaker impedance/amplifier impedance. LA90 has 0,003 Ohm in stereo.Do someone know the damping factor of the LA90 ?
Hi - I looked and couldn't find it. Where did you find the 0.003 figure?DF = speaker impedance/amplifier impedance. LA90 has 0,003 Ohm in stereo.
8/0,003≈2,7K. Not bad)

Thanks.
Thanks - not sure how I missed that.

Probably not much audible in practice.Yamaha A-S3200
Damping Factor ≧ 250 (1 kHz, 8 ohms)
What does this mean? 2700 DF from Topping vs 250 DF from Yamaha.
250 is already good enough.Yamaha A-S3200

Try it.Hi, noob question - I recently picked up an LA90D to replace my AIYIMA A07, but I’m unsure if the power is enough to drive my KEF R3 alone in stereo mode. I think the Discrete is just slightly more power than the AIYIMA given I drove it with the included power supply? If I wanted to go for two LA90D, is the process running both in pass through mono mode and adding a preamp or are there other setups? Does anyone have any recommendations on power needed then for KEF R3? Is the one LA90D enough?
Is my understanding of the two LA90 setup right? That I would use them in pass through mode and use the volume on my e.g. topping A90D as a preamp to control volume?Try it.
In the bass region where you need the most power, the impedance of the R3 is pretty low (<4 ohm from 40-60 Hz and 110-280 Hz).Is my understanding of the two LA90 setup right? That I would use them in pass through mode and use the volume on my e.g. topping A90D as a preamp to control volume?
And yeah I’ll be trying when it arrives. What kind of things would I be looking for to know if the speaker is being underpowered? I have a UMIK-1 so I can do very basic measurement but my room has poor acoustics so I’m not sure it would be super enlightening.
