Oh hey, I'm a new reviewer my self as well ^^ just doing the finishing touches to my 9 Testing songs now!
I also started out as a bass head ^^
Things I Value are
Decay- the change from high to low, a sound that lingers too long has bad decay and will be smoother but not as punchy or detailed [or clear] imo
Highs- Smoothness, air and detail/decay
Mids- Punch, Push and Detail decay
Bass- Tightness and placement [I like deeper less forward bass]
Sound Stage /Imaging -2D and more importantly 3D placement
Dynamics- Changes in high to low [part of decay in a sense]
Utility- Fit Comfort and Ease of Use
feel free to check out my blog [it links back to my Head Fi reviews] BUT I love reading reviews and I'd love some feed back on my own :D
And I agree Darker headphones are usally warm and smooth, but lack decay and air in the treble
As for the songs I test with [they are just as important]
Warning: Music (Click to show)
Lisa Edkhal- Female Vocals, Mids and Sound Stage
Move 恋し(Love) -Male Vocals, Mids Dynamics [I really like the Gusto in the Singers Voice]
Modern Jazz Quartet- Reunion Blues (W)- Mids, Bass, Treble- 3D imaging, Sound Stage [this has a very cool bass and Cymbal riff. Bass in your right ear treble in your left. Warm Xylophone right in the middle. Drums and bass sound farther away than Xylophone [it's not forward in terms of Frequancy response but rather imaging!]
HAYA Band [Mongolian Singer] Missing You- 2D sound stage, Mids and Dynamics- a really nice warm guitar in the right, and a equally warm Cello [interestingly enough my dt 990 really kills this song, as the Bass in the Guitar is WAY to strong... it's really overpowering the Punch of the mids]
Nu Tone- Mission Control- BASS and BASS? And MORE BASS and some treble Detail <3- Classic DnB Tune Keep it tight and it'll sound alright!
Anne Gastinel, Francois-Fredic Guy- [Beethoven: Cello & Piano Sonatas #2,4 & 5 in G Minor]- Treble, Dynamics, Mid Punch- Sound Stage 2D seperation.
3nd-Algorythm- fun rock tune, needs a balance of bass, mids and highs. Once again the Dt 990 is too bassy, and the mids lack punch. While the upper mids are drowned out[still a very fun song]
Seven [Binaural] Purple Bass Tighness and 3D Imaging, a really cool Binaural recording! Great for 3D placement,
Benga- Evolution [Mids, and BASS] The wobble really needs a mix of good PUNCHY mids and DEEP bass, not to mention the song opens with a sweet mid heavy intro! Highs here are important as in PURE AGGRESSION, This Dub Step tune needs to b edgy, aggressive and TIGHT [things the DT 990 does like a dream]
In addition I use my Modded w1000x out of my oDac- Matrix M Stage [LME 49990 op amp] as my reference headphone. And as always I use FooBar WASPAI Even, with 16 Bit lossless files <3 Through Coaxial cables :D
Personally I really enjoy doing reviews, heck I buy and return cheap headphones just to review them. And on a positive note, Tommorow I'm emailing a member of the Audio Technica Publicity staff on getting a review sample! So once I get through that, I'll be back here to share with you guys what all he asked of me, So you guys can get the chance maybe to do some reviews from a BIG company as well ^^, not to mention I have an AKG K550 and Ath A900x [I purcahsed my self] on the way too. So my Blog/Head Fi accounts are about to xPlode
Still, I'm glad you started this thread... I'd love to see what qualities you guys look for :D. And I shared as much about what I do, so if you see something you like you can copy. That's what I've found to work best for me. ^^ Non the less what a fun hobby we have!
