Some users are finding the 445 too lean for their tastes and transitioning to 2A3 or 300B based amps. Based on early user descriptions of the Yggy and what we know about the 445, it may not be the best combination for those looking to actually enjoy their music, especially the non Diana Krall/Cookie Marenco fare.
Half of hifi gear is designed for exclusive use with albums containing a guy playing a closed mic'd oboe in an abandoned cathedral, binaural panning songs with hand drums and the occasional meandering stand up bass line, while some born again peruvian on LSD noodles around on his hemp and bamboo pan flute. Recording costs $60 through an audiophile label, and some retired audiophile physician going through a divorce caused by his hobby is super happy to show his listening room to the first guests he's had in 6 months. Great care is taken to ensure the shed he's converted into a listening shrine is as acoustically dead as possible, but that may just as well describe his interest in exploring new music at this stage in his life. The audiophile takes great care to set up everything just so, to give his listeners the same epiphany he had in college in the 70's listening to some Klipsch horns in a music shop. He had long hair back then, and was with it. The album cues up, the pan flutes are noodling, a vocalist is not actually singing, but breathing into the mic now and again as if gathering wind for the next verse. "See, you can hear every nuance of their breath!" He exclaims. The listeners are in a now nearly comatose state of boredom despite being informed of just how old the tubes are, the audiophile lineage of the speaker designer, and how cable riser risers are the newest thing, as they prevent the cable risers from having any adverse affect on the cables. (The floor is lava!) One listener pulls up a TV on the Radio track on her cell phone and asks if they could listen to it. The audiophile arches an eyebrow and folds his arms in a move he learned from the dealer who sold him his audiophile barometric pressure equalizer (since sound is waves and travels through the air the air itself is what causes the most degradation to the sound) as if to say "I'm not sure if you can be an audiophile and ask that." Since the listener doesn't care if they're an audiophile they plug an auxiliary cable in and crank it beyond the audiophile recommended amount of decibels. The listeners are enraptured by the song and proceed to dance. At this point the audiphile has a vein pulsing in his forehead as his listeners are no longer in the sweet spot. "You're missing the whole point of the setup!" He intones. "The reflections are hitting your ears at the wrong angles! You are not optimally placed to allow the speakers to do their jobs to the fullest!" Yet they continue to dance until the song is over and start another, as they have not yet forsaken music for sound, nor living for reminiscing. The audiophile gibbers. He did not spend $800,000, countless hours at dealers and shows and 20,000 internet posts to find out all his triumphant decisions made in his long, smug journey were counter to what he initially upheld as his blissful destination.
Then he realized this is how many people feel at the end of their life and the epiphany could wait until his deathbed, and went back to an audio forum and posted about the clearly negative effects of fluorescent lighting on a listening room.
