Up for sale is my Audio Research LS16MKII preamp with remote. It's in excellent working condition. Sounds fantastic! Gave it 7/10 due to age. Included are two Sovtek 6H30PI and two Electro-Harmonix 6H30Pi Gold Pin tubes. The Sovtek have approximately 10-15 hours. The Electro-Harmonix are brand new and have not been used. Both are matched pairs. Was going to use it in my second system but went another route. Asking $1600 + $50 for shipping. Or best offer. Local pickup also availablel. Ask any question and I will do my best to answer.
