Bottom Line:   
Overall its a good home, portable pocket amp, and cmoy amps dont compare and i didnt see any products with a lower price that came close at all,however a little more money you can get a little better amp,on up too tube burning $2500.00 if you want,and i guess electro static headphones if you want too pay the ransom demands!
I JUST NEEDED A LITTLE MORE VOLTAGE for 250 ohm headphones ,too feed the bass requirement ,and the grado 80s have a serious bass deficit going on ,not the dt-880 pro models though,but it did get a little stronger and still really tight bass resolution too!
After hearing a standup bass recording sound better than i could have ever imagined, i wanted to make sure i had enough voltage leftover too resolve complex deep bass passages!
At this time i couldnt spend any more than this.
I am pleased with this little xm4,its packs alot in a small package!
