MasterSounD DueVenti S.E. 220 Single-ended Class-A stereo integrated amplifier 1 pair of EL34 tubes handle 20 watts of power per channel and run in a single ended design. Features:Auto Bias Soft on/off feature 5 inputs1 variable pre-out (subwoofer output)4ohm and 8ohm speaker terminals with top grade solid copper binding postInhouse and hand wound transformersProprietary circuit board with thick tracesHand point to point soldering using high quality sleeved copper wireGold plated RCA binding postsUpgraded NOS tubes for both power and pre-amp section. Tubes are : 4 NOS SED / Winged C EL34- $480 & 2 GE ECC82- $42 Wood is in fantastic shape and is NOT a veneer. Its a solid block of high grade mahogany stained and sealed in a natural finish. Amp was recently cleaned and stainless steel plate was polished. Fuses were replaced with fresh units. Comes with printed manual and original shipping box These models did not come with a remote until 2008. Again the manufacture did not want a power volume knob in the the amp until there was a unit that could provide the quality they were looking for. Automated knobs at the time could impact sound quality and wanted a manual / analog operation for best sound quality MasterSounD is a very well respected amplifier manufacture that tries to do as much independently as they can. They do believe that the details in the signal path matter and will add up. This amplifier does NOT allow for any KT77,88,or 100 tubes. MasterSound was very particular about this because the circuity that would be needed to allow for the swapping of power tubes would not create the sound profile they wanted from a single ended Class-A design. This is why they kept the KT88 and EL34 models separate (DueVenti and DueTrenta). Despite it being ratted at 20 watts, its presents with a lot more powerful and authority than that. I expect this has to do with the hand made transformers and its single ended operation Its heavy! 50.70 pounds w/o box This is review is for the same model but with some minor tweaks to allow for a remote control and a different input selector which reduced the inputs. https://6moons.com/audioreviews/mastersound2/duo.html MSRP: $5,495 USD / $6,995CAD
