Item Condition: Excellent 9/10, show minor signs of use, also includes boulder customised power cord adaptor which allow you to use high end power cord. Reason for selling: Downsized to Bookshelf, NLR
This great amplifier needs no introduction. It has superb engineering and build quality, has enough power to drive any speaker load, is tomb quiet & very natural sounding. I have enjoyed my time with this amplifier tremendously, but I have now downsized to bookshelf speakers, no longer required this monster. On the technical side, the Boulder 1060 is a true differentially balanced, direct coupled, dual mono, class a/b amplifier which operates in class a for the first 17 watts before switching to class ab. Boulder put a lot of effort into perfecting the circuit design (including the biasing) and spent a lot of time notching out crossover distortion. As a result the 1060 is linear in operation like a class A amp.
The design and specifications of the 1060 are just astonishing. Virtually every component of the amp is designed and manufactured in-house (Including the cad-designed cnc machined/hand-finished chassis), whilst those that are not are custom-made to Boulder specifications. Nothing is off the shelf. The 1060 features twin potted 1.5kva transformers, bridge rectification, 48 filter capacitors (24 per channel), 56 bipolar output devices & Boulder proprietary 983 gain stages. Protection circuitry is also reassuringly robust. Boulder guarantee 300 watts continuous power into any load, but the 1060 feels more powerful than that and one suspects that figure is conservative. But for all that power, the 1060 only pulls around 60 watts at idle, and 15 watts in standby, meaning you are not hurting your power bill (or the environment).
This is an amp for a serious audiophile & is capable of amazing sound matched with a good preamp and cables. The the input impedance of the 1060 is 100k ohms (balanced) or 50k ohms (unbalanced) which is benign to even the weakest tube preamps.The 1060 is a high input impedance amp, so you don’t have any impedance mismatch issues.
This amp is a 240v Australian sale example (not converted from 110v). It comes with original wooden crates.
