In reading some other's opinions about the VR-M90, I'm a bit disturbed. More than one person has said they felt the vocals were flat and the mid-range a bit strained. I will say they were pretty flat right out of the box but I have about 100 hours on them now and they have really opened up! I have a Sony 300 disc changer using an outboard Entec DAC. Source, IMHO, is one of the most important, if not the most important, pieces of your system. That is where everything starts. If your source is crap, no matter which amp, which speaker, which cable etc., it's just not going to improve a poor source. The Sony without the DAC is dull sounding and just not very musical. Run a good toslink to a quality DAC and WOW! I am a firm believer in when it's time for an upgrade, start with the source! Also, before being too critical of a new piece of equipment, especially speakers, give them time to break in, you may be pleasantly surprised.
