Hello,
I own a Topping A90 discrete headphone amplifier and a DX3Pro Plus that i'm using as a DAC (RCA output). My Headphone is a Hifiman Edition XS (18ohm/92dB) connected to the XLR balanced output of the A90D
I'm interested with those DACs (for full balanced chain) :
- SMSL SU-9(n) (XLR: 207Ω RCA: 142Ω) [mesured by Amir - XLR: 370Ω , RCA: 122Ω]
- Gustard X16 (XLR: 300Ω, RCA: 100Ω)
And the Topping A90d has 2KΩ for XLR and 10KΩ for RCA input impedance. If i'm correct, the ratio 1:10 for input/output impedance is not respected in this case ... Is it very bad ? What can be the nasty things that can happen in this case ?
Thanks for you help and your knowledge !
