Where I’ve Been Lately


I’ve been quiet for a while here on the Passion for Sound blog due to a little personal project I’ve been working on over at Head-Fi. Some of you will have read my review of the assembly and performance of the Bottlehead Crack DIY tube amplifer and you might have also read my assembly review of the Bottlehead S.E.X. amplifier too. If you’ve been waiting for the performance review for the S.E.X. then you’re in for a treat! Not only have I completed a thorough review of the S.E.X., but I’ve also built and reviewed Bottlehead’s premium, top of the line amplifier, the Mainline. I’ve compared each of the three amps to each other as well for anyone who’s unsure of which amp is for them.

Rather than post the same reviews here or take the time to redo them, I’m going to share links to the review on Head-Fi. Don’t worry, you don’t have to be a member to read the reviews, but you will need to sign up if you want to comment (it’s free to sign up and it’s a great community). If you have any questions or comments, please feel free to post them here.
