"It's colored but it's color only sounds attractive through tubes. All headphones aren't tuned for SS amp sound, or the 50,000 Sennheiser Orpheus wouldn't be paired with a tube amp. Other colored headphones sound better with SS amps sure, but NOT the hd650. The hd650's coloration only sounds properly engaging through a tube amp. This is the 90 percent consensus. That's because it lacks low and high energy that it has to sound lively somehow, a sound it doesn't achieve through 99 percent of SS amps. I am sure that because the 650 is a modified 580/600 it was also originally designed for tubes and warmer systems, as the tech is decades old and commonly used in systems much warmer than we are using today. It really does sound absolutely *insert curse word here*ing and flat with no detail through SS " You really dont see that even if that would be correct you would support my point? It is Preference, if its a Company house sound (relative believe of their concept of good sound that is different from Company to Company) or if some hifi group mostly likes something some way its still relative and subjektive. Its not absolut and "just" true. Example : If the 70 or 80 or 90 % actually like elevated bass more than linear bass, than isn't elevated bass universal needed for good sound. Its a question of Preference like "attractive" may indicate . We can get measurements of accurate reproducing, but we cant actually find the universal good sound. We have very different concepts of good sound, like we have with everything that is perceived 'good'. its seems everyone likes different. "And please don't assume my preferences as I hate U and V signatures, Just because I don't like the mid-oriented hd650 that fails to resolve good bass and treble, doesn't automatically mean I like V-shaped, lol." I wrote "if". I didn't wrote that you do. The hd 650 has relativly elevated bass and mids, its not just midoriented. "Or Sennheiser is stupid, Lmao." no there trying to make a profit. This sounding seems to be trending in their target group. "Sorry to argue when you're wrong but this one's not up for debate." Please don't do that. it isn't true just because its written. Actually we are debating. Coloring and inaccurate measurements aren't really compatible with the "High Fidelity". the Term "Music or audio enthusiast" could be more accurate to describe this group of preference .
Well, modern SS, if good constructed are mostly straight linear, transparent, with very great measurements > the music sounds as indented. Not everybody likes his music presented this way, even if it is most likely the technical "correct" audiophile outcome and hopfully enjoyed experience of youre file, simply because sound mixing &producing mostly uses linear equipment in the chain and this way you could hear what they are hearing. If you would use a linear chain at least. But the 6xx isn't fairly linear , its quite colored. That is what I call preference, its how you like youre sound, it is exactly what "incredibly boring, no treble activity, no low bass" I guess means for you> the coloring of the 6xx isn't enough for you. And as far as I would go> that is the way to go, if you want a U or v shape signature because its you're preference fine, finde the headphone you love. Simply because coloring HP and linear HP are often more comparable quality wise and HP ( or LS) are far more important for the overall sound than every other part in the chain as long its decent. But there other ways, some people use EQ with great effect, some tube amps. Sadly tube amps aren't just colored there often measured worse than SS. for example If you balance you're HP with an Tube, you get youre coloring but likely worse measurements  too. For every HP you use on this amp, even for HP you like maybe more on SS, the coloring will be constant and the measurements  worse. Some people are buying for every HP a new Amp. I think its ineffective. buy one chain that is measured well and is linear and add color (if you like) with the most important part how you like> youre HP. buy worse and buy again and again to balance coloring with coloring. "It's been the collective consensus on head-fi for over a decade that the 650 sounds good at best from a SS." Im glad that for once head fi agrees with my taste ;-) it sounds good . "If you think the 6xx sounds amazing from any SS setup well, frankly you don't know good sound." Still bullshit, good sound doesn't universally exist, its simply highly subjektive. Sound performance can be measured but that cant predict with certainty if the same sound is liked from someone. The tube fraction is prove of this. Its measurements ( performance) +/ o.Preference: "good"& enjoyed sound.
