DT990 Pro Impressions Thread
Mine are old, and I noticed when I push ear cups to ears sound is better better mids and bass. Is that the difference with new pads as well? I am cheap and wondering what difference it will really make.- Bassman999

Im not sure if covering the whole driver wont make the sound seem veiled. I think increase the size till it is enough attenuation. extra foam may or may not help, but I think its pretty acoustically transparent. I have the 600OHM, and not sure if they sound different, but am also 43 and...- Bassman999

I have read someone removed the foam and placed a small piece of tissue under it, and experimented with layers and size till he got the upper octave(s) in question softened or to his/her liking.- Bassman999

@dw123 I think the premiums I have could be a little tighter and be fine still. The force seems even to me. I am a person that get headaches easily, and these dont do it to me even after hours.- Bassman999

I got a used cMoyBB on eBay, and a newLIttle Bear P-1 (from China) hybrid tube amp. Of the 2 the Little Bear is more powerful, but the Cmoy sounds better. I dont have experience with other amps. I think the Cmoy actually powers it really well with the OPA2227 inside it.- Bassman999

I tried to listen to the same songs as I was last night and this morning on the 990s, and found that my car has terrible mids and mid-bass. EDIT well the tweeters sound bad as well....Just everything above the sub-woofer is bad! I turned off the music and went to a different genre out of...- Bassman999

I more thing I forgot to mention is that I LOVE the drums on these. I mean they go low and have the perfect Timbre IMO. Snares and toms and floor etc. I didnt realize how much detail I was missing!- Bassman999

I am noticing the same thing. If the original has too bright a recording so will the playback and the inverse is true. But I have found as many say with hp's or new speakers, that I hear new things in my songs, and partly because I am listening to higher quality now in part. I suspect. I am...- Bassman999

Best sounding cheep op-amp for CMoy's? OPA2227, OPA2228, AD8066...other?
I dint think I would go that high anyway, but the choice was up to 12V or up to 25V for the step ups. Although even at 12-18V I could use a few 3.7V in series for higher Voltage.- Bassman999

I grabbed the 900mAH with protection and a charger. I am going to go with the adjustable step up that goes to 25v, since the caps are all 40v and 50v rated- Bassman999

I use mine with my cMoyBB v2.02, and my hybrid Little Bear P-1. I plan to upgrade later on. I also use the phones out on my Denon AVR-3801- Bassman999

do you use a high capacity 3.7v LIPO batter like 1200 or 4400 mAH or small like 500mAH I saw this charger.. Simple and cheap- Bassman999

Ok so the weak link in my cMoy and its ability to have a higher rail voltage will be the caps... Ill look in there and see what its comprised of, and if I can mod this thing. I cant do a from scratch one I dont think based on my poor vision.- Bassman999

I just got an answer to the 2nd question by reading the specs , that input V cannot exceed output V for fixed value, but can be for the variable ones.- Bassman999

I have to update my opinion of these cans now. Listening to low quality 128kbps and under MP3 these sound ok, but higher quality and these come ALIVE!! I am very happy, even using my cMoyBB with these 600 ohm'ers does a great job. I am having trouble keeping the volume down as they...- Bassman999
