Hmm...I don't find guitars to be that forward, but then I'm not listening to Metallica.
Just listened to some Metallica.
The good: Drums and guitars sound great. Drums sound very clear and distinct with excellent separation. The guitars are very forward with just the right amount of crunch. Very detailed and grabbed my attention the most.
The bad: Vocals and highs sound unnatural. Very unnatural. The tone of Hetfield's voice is completely off the mark. The weird thing is that there a veil specifically over the vocals. The highs lack energy, brightness, sparkle, and extension. The absolute strangest sounding highs I've ever heard.
For me, it's a mixed bag of good and bad.
