I've been very vocally supportive of the HD 8XX in the past as the concept of the tuning(less treble, more bass) was something that I did want. In fact, the first few reviews not from Crinacle or DMS had the retuned headphones in a fairly well positioned place. Purr1n had great things to say about it. Once Crinacle's review came out though, it seems that general sentiment towards the retune shifted into the negatives. Over at SBAF, Purr1n made a very good point about all of this: Everyone who reviews headphones has their own preferences.
While Purr1n and Crinacle agreed on certain headphones, they'll disagree on others based on tonality. Similarly, DMS and Crinacle had certain headphones they'll have different interpretations on as well. For instance, for their reviews of the Audio Technica M40X, DMS calls it a V-shaped and analytical headphone while Crinacle says it's neutral with a bass boost and has very poor detail and imaging. There was someone on Drop who loved to shit on the HD8XX based on the graphs and bragged about their LCD-X purchase but doesn't seem to realize that Crinacle gave the LCD-X the exact same score as the HD8XX with a D- in Tonality and an A+ in technicality for a total score of C-. Purr1n had stated that the HD8XX would be great for people who like the Audeze house sound ironically enough.
In the end, sound is extremely subjective. I generally try to look at reviews with a grain of salt knowing that one person's view, or hearing in this case, would not match mine completely. To that end, I resolved myself to hold onto my order as the price was still reasonable. I was never going to use the balanced cable supplied by Sennheiser anyways as I bought one from Hart Audio Cable already. I wasn't able to find something I was willing to get for the $200 in Drop credit up to this point but I figured I would find something eventually. At the worst, I would order a key cap set or something. At $1,100 + tax, it was still a pretty good deal even with the scoop in the mids.
Having said that, it's tough to pass over the deal from Sennheiser especially with the $200 in Honey Gold. This makes the original HD800S just $100 higher than the 8XX when factoring in the extra 4% cash back. To this regard, I have canceled my HD8XX order. Instead of trying to find something on Drop to spend the $200 credit on, I can convert the Honey Gold into Paypal credit to directly pay off part of the headphones as opposed to buying more items. And, as loathe as I am to admit it, but I felt safer in a way buying straight from Sennheiser. If Drop changes the tuning or this is revised to the HD800S at the end, I’d be conflicted.
Edit: I should add that Drop being $100 cheaper is including the credits on both. If we're looking at pure out-of-pocket costs, buying it straight from Sennheiser could be cheaper since you can convert the Honey Gold to PayPal Credit.
