@audioconnection Thanks again John. I have done everything stated above. I am looking for other owners opinions/experience. I have AQ Robin Hood bi-wire cables in the system now. Built Class A EL-34 tube mono blocks (awesome), my DHT DAC which you have heard, our custom built 6SN7 preamp using a Metronome transport that has a separate power supply. To my ears, nothing can touch it but I am always looking to hear from other owners for their personal experiences. For me hearing the Vandersteen model Sevens from the person that you know and sold the Sevens to, that is my speaker of choice if/when I would consider another level up.
Happy Listening.
