Next up were the Russian Mullard CV4004 stock tubes. This was better. Less detail, sure, but a more fully rounded sound and no hole. I could live with these tubes. They did nothing wrong, but also did not do anything outstandingly well. Just solid-sounding tubes. Maybe it was not terribly surprising, but these sounded similar to the Mullard 12AX7 tubes from Great Britain, and it was six of one and half dozen of the other – between the two. Best to go with what is available and less expensive.

The next tubes just smoked me, the Amperex Bugle Boy tubes. I was not prepared for this degree of difference. Unlike the Mullards, which did everything very nicely, these tubes did everything exceptionally well. Darn, the guitars sounded like musical instruments instead of a copy of a guitar. What a fantastic sound stage, wide and deep, and “Yeah, I am a sound stage freak,” and these delivered. Powerful low end, both the low bass and the mid bass. Very lifelike male and female voices. These tubes simply had no weaknesses. Sign me up for these. Now I wonder what they would sound like in my McIntosh C2200? I do not want to know because they are not inexpensive tubes, and I’d need four of them.
