I'm new here (as a registered user) - so I guess this is the forum where I should ask my first question...
For the past two years, I have mainly concentrated on getting back into the world of HiFi at home after a hiatus of about 15 years: I've revived my Revox B285, got a new (old) TD 2001 and a nice pre-amp, etc. etc. Now I'm in the process of upgrading my music experience at work - which is where headphones come into play.
I have an ancient DT990 - bought in 1985 or 86 if I remember correctly. With some new earpads, they are now back to their old glory, and I'm very happy with them. At the moment, I'm listening to music at work with the following gear:
- MacBook Pro (Retina), with Audirvana plus
- SMSL SAD-25 (a digital Amplifier + USB DAC + Headphone Amp)
I'm now considering an upgrade to a "real" headphone amp and have also been toying with the idea of getting a tube amp (simply because I've never experienced tube sound and am curious). One option that I have stumbled across would be the new Little Dot MK 9. (I'd also need to get a decent DAC then, of course. I currently have a USB Thingee at home and would probably use this until I get a second DAC.)
Apologies for slightly rambling on, but now the question(s):
- I don't know which version of the DT990 I have. I've been told that they made both 250 and 600 ohm versions back in the '80s. Does it matter for my choice? And if yes, how do I find out?
- am I likely to hear a noticeable difference from the SMSL SAD-25 (given the rest of my gear)? I'm mostly interested in an improved soundstage effect. Or put differently: is the LD MK9 + DT990 likely to be a suitable combo?
