Best 300$ DAC for Sennheiser HD650 and OTL Tube Amp?

[dragonball]

In today's times, which DAC will be best in terms of Sound Quality for HD650 + OTL tube amp (Eg. Bottlehead Crack) ?

I dont need MQA, balanced inputs, etc.

Thank you

I like my SMSL SU-8 with my Bottlehead Crack + Speedball. Honestly though, switching through DACs doesn't really change my sound much... I've used this one, a cheap-ish Liquid Spark, a Schiit Modi 3+, Dragonfly Red... really, at the end of the day for me it comes down to the DAC having the right inputs and outputs to fit in my system (SU-8 has balanced XLR and RCA outputs, which is a must for my setup).
