Is Topping A90+Topping D90 combination worth the extra 700 USD when compared with the Topping DX7 Pro alone? Which should I choose. I have Hifiman SUNDARA and Sennheiser HD 800s headphones.
Thank you

For your headphones consider upcoming D30 Pro + A30 Pro? They are just recently reviewed.
Thanks

Yes, in my opinion, you are getting more for the money, you get more power and the option to upgrade the dac or the amp in the future.
The A90 is a better amp too. You can always get the A90 and the cheaper dac for now, you can get a great balanced dac for 200-400 dollars.
The SU-9 is probably the best balanced dac (last time I checked), Ghessheli labs also has a balanced dac thats 250 with the USB card.

or like Veri said wait for the D30 and A30, those look great too, depends how much power you need.
(Topping-A90)
Looks like like someone has had the same problem as the L30 that fries both the Amp and the headphones too.

Can you give any advice on how to get it open?
I've got the back panel off, every screw undone but the cover will not budge no matter how hard I try.

Very simply put, some users here and elsewhere reported that L30s had failed and destroyed some HP drivers in the process. Topping investigated and found that the L30 could be vulnerable to high static shocks (more prevalent in dry winter months) which coould cause components to fail. DC current could then flow to the HP at levels far in excess of tolerance , killing the drivers.
They have amended the design and build (units with serial numbers 2012XXXXXX and on), offered exchange via retailers to anyone with a S/N before that. New units have been arriving with users the past couple of weeks.
Use that info how you wish. The bottom line is that amps can fry headphones in the right (wrong?) circumstances. The real challenge is knowing what controls are built into any given unit and how effective they are when faced with extreme conditions.

Does the A90 put out more raw power then the Benchmark Audio HPA4?
It does.
