I sucumbed to peer pressure and took the plastic body off my Dynavector 10x5 phono cartridge. It's airier and the soundstage is deeper and has more ambience.

Just for the hell of it I bought 2 of Herbie's Tube Coolers and put them on an important component, the Cornet phono stage, but only the 2 least important tubes. I liked it. Now all 7 small signal tubes have them. Big difference on the 2 5751's in the Rogue, medium on the 5965's in the 45 amp and low on the 2 12AX7s and 1 12AU7 Cornet.

It's all the fault of the 45 amp with its ultra-real sound which reveals everything. That and waking up every night at 2 or 3, unable to get back to sleep and prowling the web with my debit card nearby.
