SA20 Integrated Amplifier
Arcam's latest high-performance integrated amplifier
There are two frequent problems with hi-fi amplifiers. Class A, the traditional audiophile’s choice, uses a single power supply constantly running at full capacity, even when there’s no signal coming through. Great for reproducing those subtle details at low levels however struggles to provide extreme power when needed.
Class A/B, the most common amp class, switches between the two internal amplifiers, one for each half of the waveform. Far more efficient but often a recipe for crossover distortion, since those low-level details we crave can get lost within any mis-match between the two switching over.
Class G is essentially a hybrid amplifier, utilising Class A specifically for low-level signals, but when required switching in an additional power supply to power those larger sections of the waveform.
Once again thanks for your help. I first visited Bartletts in 1993 and bought the Audiolab 8000a to equalise and compete with whatever the neighbours were playing at the time through the very thin walls of a Victorian Mansion Block. My Quad at the time although could musically could not compete. I had bought the Quad in 1984 at a place in Camden by Mornington Crescent, although I felt that I bought what" that particular shop "wanted to sell me rather than what I wanted.
Firstly delivery was estimated at 7-11 days - it was actually delivered by courier the next day (Free). Item was an excellent price and although it was advertised as used - it was absolutely mint. This is what internet buying should be like - well done all at Bartletts!
If I could give Bartlett's 10 stars I would....Quite superb service (a special mention for Simon here) - Buy from this supplier with complete confidence.
