Hi what amp would be cheapest to drive DT 770 250 Ohm ? I prefer portable as for TV and phone but mostly used on PC. On some topic I seen it need 260mW to drive it properly ? I don't need much volume. HD 598 are good at 25 volume but they are 32 Ohm and open.
TOPPING NX1a is 30€ but it says it's only 100mW
Biggermouth A2 $30 860mW but says load impedance is 2K Ohm so how do this impact on headphones and battery ?
 
 
I am wondering about response. It have any impact on headphones as this cheap amps have only 20-20Khz-30Khz response and DT 770 have 5-35Khz

Used DT 770 250 Ohms are 80€ (owner says it's used only for 3 "radio interviews" While new DT 770 80Ohm and 250Ohm is 135€ So probably used is best deal as headphones are durable. I am not sure about warranty Is there a lot of chance speaker die ? as they are quality headphones. I would pick 80Ohm but ppl on forum are saying it have heavier bass.
Beyerdynamic Custom Studio are 180€
 
Thanks,

The Topping will be fine, ive used it with DT150 and its loud enough.

It will be fine even with only 100mW ? Do I also need DAC ? So different response it not a problem ?
I see SMSL m2/mini are $50 with 130+130mW what this means ?
Fiio A3 is 60€
Anyone familiar with Biggermouth A2 or A4 I don't find any topic at head fi

I guess used DT 770 250 is worth 80€ then and $30 amp

Ordered one out of PURE BOREDOM.. just to see how they sound off my Darkvoice amp. I f I hate it.. Hopefully returns are not a pain or it's Ebay city . And I'm sure I'll like them. (fingers crossed)

well.... they've arrived. My quess was since OTL Tubed amps (like my Darkvoice 336se) drive high impedance headphones the best... to grab the 250ohm Beyers. This pairing sounds really special folks, my Sennheisers are super jelly right now. Currently rolling with Mullard 6080 & Sylvania VT-99 tubes.. WE 421a & Black Ken Rad 6SN7GT, very smooth.
