Hello, I enjoy listening to all sorts of music. Music has played an important roll in my my life. I grew up in the early 1970's when there were a lot of good bands from all over the world putting out great LP's and doing a concert tour after each release. I was lucky that I was able to see the Who and Led Zeppelin along with many others. I recently bought a DAP with matched IEM's with a 4 wire system. There are 2 wires running to each monitor, it has a 3.5 mm jack with 4 sections. The IEM's and the DAP are made by the company HiFiMan. I have the HM-700 and the RE-600 Songbirds After listening to my music collection with the high end portable system I want/ need to upgrade my speakers. That is why I am on the forum looking for help in finding the best speakers for my needs.
