100+ Head-Fier
For tube amps, the only others I have tried with the Utopia is an Ampsamdsound, a Woo OTL, and the Feliks Envy. I own the first two and neither would be suitable as the first is noisy, and the OTL is rated for 300 ohm headphones like the Senn. I listened to the Envy at an audio show, it was quite nice combo, there was a bit of noise but you have the option of changing the gain levels to reduce.Unfortunately the DNA aren't readily available in Germany, do you have any other pairings you can recommend?
For solid state amps which leans a bit warmer, Bryston BHA-1. It’s an oldie but goodie amp which due to its age folks seem to disregard it. I’m sorry if that is not helpful, not familiar with which amps are available in Germany.
