Morrow is silver plated solid core copper and I have no idea how pure the copper is and Speltz wire looks like common magnet wire. As far as speaker cables go the Morrow SP3 or SP4 is well above the magnet wire. I have not tried the Morrow ic's but I did have a couple pair of anti cable ic's a few years ago. They are a bargain. Another good deal is the Vintage Audio Labs pure silver solid core ic's on ebay. I am pretty impressed though with the Morrow speaker cables so my feeling would be to try the Morrow ic's.
