First of all, I have read this forum for a few weeks and feel that the people here are incredible knowledgeable with top-notch advice. Therefore, in my first attempt at building a headphone system, I seek your advice because I have reached an impasse.
Here is the current equipment I have now: DT770pro 250, DT1350, Aune T1 (eh6922).
I have given everything at least 40 hours of burn in.
I listen to a mixture of loss-less, high and low bitrate mp3, and spotify.
I listen to every genre of music. In any given day I will go between indie acoustic, mainstream acoustic (ie mumford&sons), blues, orchestral, dubstep, hard-core death metal, power metal, country (new and old), blue grass, electronic, folk, classic rock, and hip-hop.
Here are my requirements:
-Must be closed- for office use
-Bass quality is much more important to me than quantity
-No sharp treble ie. sibilant type sounds. Which probably means the system must be more tolerant of some of the more low-quality sources I listen to.
-Price is a factor, would like to keep the phones under $225 and the DAC and AMP or combo DAC/AMP under $300
-Have no preference for over/on ear. Tube vs solid, or portability.
Here is what I have found with the current setup:
-DT770, Bass- a lot but I can live with it, Mids- far to recessed, Highs- Cannot stand them, way to harsh and sibilant (with both high and low quality sources). Love the soundstage
-DT1350. Bass- what they lack in quantity they make up for in quality, Mids- too forward, very bothersome to my ears, any track with a piano drives me nuts. Highs- not sibilant at all, sounds very pleasant. Comfort not a factor. Would prefer a larger sound stage but not a deal breaker.
-Aune T1- have no other comparison. May or may not be part of the problem or solution.
So, I am looking for something that solves the treble problem of the dt770s and the mids problem of the dt1350. If changing components could make either of these two phones fit my preferences or if the T1 would fit any of the phones below, I am very open to that as well.
I have done significant research on this site and others and have loaded up a cart on Amazon based on that research with the intent of trying the various combinations. I would really rather not spend that much money and have to deal with all the returns. Therefore I am asking you all to help me narrow down my choices. Here is the equipment I am considering:
-Audioengine D1 (also an amp)
-Audioquest Dragonfly V1.0
-Little Dot Mk II
Thank you in advance for your advice
