Ars-Sonum Gran Filarmonia

Ars Sonum Gran Filarmonia 60 watt integrated tube amplifier. I am the second owner and purchased it from Richard Brkich of Signature Sound in Liverpool, NY. Rich is the Ars Sonum importer. I purchased it in October 2018 and it was manufactured 12/15/2017. this is the latest version. The amplifier is still under the original warranty until 12/15/2019. It has performed flawlessly and sounds amazing. I am only selling it because I want to use a pair of speakers with a 4 ohm load. The following is the description on Signature Sound's website, " This amplifier is hand crafted and made with very high quality parts, materials, (hand wound) transformers, and more. All lovingly put together by designer/engineer Ricardo Hernandez in Spain. The Filarmonia uses a special screen grid regulated pentode circuit and a low 6dB of feedback to deliver 60 watts of glorious sound.  The Gran Filarmonia is the culmination of what was learned on the Filarmonia SE and expanded for greater power and more expansive sound. The Gran Filarmonia uses a DC coupled inter-stage configuration that reduces capacitors in the signal path. It comes with hand matched JJ E34L output tubes, carefully selected front end tubes for fantastic performance right out of the box without any tweaking or tube rolling necessary".  Additionally, this amplifier has autobias. The volume control is a very high quality stepped attenuator with expensive Vishay resistors. You can bypass the volume control if you want to run an external preamp and use the Gran Filarmonia as an amplifier only. I have been in this hobby for 30 years and I can honestly say this amplifier is amazing. It's good enough to be your last amplifier purchase and not worry about an upgrade in the future. Also, Rich at Signature Sound can perform any service or upgrades at his shop. The amp is designed to be paired with speakers of impedance between 6-10 ohms, and a sensitivity equal or higher than 86dB/w/m.  There are two small chafing marks on the top plate near the center volume control. They are small and may be able to be polished out. This is a beautiful hand built amplifier. The quality and attention to detail is very much evident when you look it over and listen to it. I have all the original boxes, packing materials, and owners manual. please check my feedback.
