*Sigh*... After a year of quitting the head-fi addiction, I am back again.
I used to own Grado SR-60, Sony 7506, Sennheiser 497, and Audio Technica A900 (upgrading slowly). Sold them all since, and now my scrappy Koss KSC-75 (kramer modded) have been serving me well off my Echo Indigo along with my IBM T42.

Lo and behold, I am considering my next headphone purchase T_T

Can my Echo Indigo's built-in headphone amp drive these cans at or close to their full potential?
- Beyerdynamic DT770 (80ohm version)
- Sennheiser HD 595 (50 ohm version)
- Grado SR-225

I searched for a few hours, reading up on these 3 puppies, but I could not get a definitive conclusion, especially on the DT770's.

Thanks in advance!
I can't believe I've been at this for 3 years (April's coming up)...

I've used my HD595 with my Echo Indigo, as well as the RSA Hornet and Xin SuperMacro-III. I perceive no difference in sound quality when using the Echo Indigo without an additional amp.

Definitely yes for the 595 and the 225. They should be easily driven by the Indigo.

I'm not so sure about the DT770.

Could anyone comment on the pairing with DT770?

I have DT770 Pros and an Indigo I/O and they work fine together -- plenty of volume for any sensible purpose.
