Hello
Save your money on fancy name brand audiophile tube amps except for may be the highly rated 6bq5/el84 based single ended Almarro that is designed in Japan and made in Asia and shipped here. Based on your personality what may be more fun is to get a single ended 2 to 6 watt amp from a old 1950's or 1960's console stero cabinet and use your current preamp. A ebq5/el84 or 6v6 based single ended console amp from a Magnavox, Stromberg Carlson, Motorola, Sylvania, RCA or other vintage console will surprise you. It may not look a smooth as an integrated tube amplified combo preamp and amp in a completed box but you will be happier with the sound. After starting with a console amp you may want to explore a tube preamp like a Bottlehead tube preamp or a vintage solid state preamp from David Hadaway's DB Systems. The Adcom gear can always be used on an inefficient pair of speakers like electrostatics designs or sealed box speakers that are 86 to 91 db effecient instead overkilling a 105 db efficeint speaker like a Khorn. A major consideration in tube amps is other people and pets in your listening area as most console amps have unprotected tubes exposed to human contact.
