I purchased an X-Combo and X-Jumper from Gary and the tone difference was unbelievable. The clarity and richness of tone jumps out at you! Gary has been an absolutely great guy to deal with and he offers some great customer service. I love how as soon as you order something through him, he e-mails you back thanking you for the order and includes all the tracking information (sounds stupid, but I like getting tracking information on my packages and I give that to everyone who buys from me myself). I just finished purchasing an X-Head cable from him and I'm looking forward to using it, this man has already shown me that he delivers an exceptional product, so I'm looking forward to purchasing more down the road. Hands down the best improvement I've ever heard for my tone, can't wait for the instrument cables to come out! Anybody else ecstatic about these cables? I'm absolutely in love with them and the audiophile side of me means I'll be getting the entire line as soon as I can afford it.
