Well folks. I know you're all waiting in anticipation on an update on the sound of my new Audio Horizons 2.0n preamp. You're going to have to wait a bit longer, because I just popped in some NOS Siemens Cca tubes and it needs some further play time now to break in more. I can say that this preamp, in conjunction with the other components, is sounding very musical and I'm really enjoying the music. This is by far the best-sounding system I've ever put together on a decent budget without breaking the bank. I am sending my main tuner( a primary source of listening for me) to Joseph Chow for a slight mod next week. I'm currently experimenting with a variety of cabling to further fine-tune my system. So far, my speaker cable of choice is the AZ Satori, but by next week, I'm going to put the PS Audio Reference back in for a final decision. I'm also going to experiment with a few power cords on the preamp over the weekend to get the right sound I'm looking for. I just ordered some NOS E82cc(12au7), Mullard and Siemens, to put in my mono amps for some fun tube rolling. My goal is within the next few weeks to have the system fine-tuned where everything clicks in. Then I'm going to post my virtual system and enjoy the music for a while. I'm very pleased with the service and communication that Victor and Joseph have given me. Victor actually rewired my power outlets at no charge. This is such a fun hobby! (~:
