Here are 2 DACs that will make a significant difference in the price range.
1) Topping D90SE. Maybe the best mesauring DAC and it sounds so clean and detailed. I love this DAC with my warm CODA amp. It costs $900 new. This one uses the ESS chip while the D90 uses the chip which had the factory fire (forgot the name)
2) The Gustard X26 Pro. I just sold it for $925 last week. It is on sale today for $1275

This is a warmer DAC and not as detaieed as the Topping D90SE or Benchmark DAC3B, but pretty close. It also has NOS | OS mode with 4 filters for each mode. The sound does change with the filters. This is a great DAC for the price. I sold it to buy the Musetec 005 which is also on sale today for $2969. So that is a big jump in price.
