Synergistic Research Tesla Apex were top of line when I bought these. No issues or problems with the IC's, I've eliminated my preamp so I no longer need these. If you're wondering, I also use (have used) Tara Labs and Nordost, so these cables fall in line sound wise for me. Shipping is to the lower 48 states only, signature required, via FedEx. Shipping is included in asking price.
