Well, like it or not, a lot of japan made high end amplifier come with built-in speaker selector! Convenience
vs compromises :)
Does any one have experience with a high-end amp switch or the Luxman AS-55
Hello all,
I am interested in the Luxman AS-55 speaker/amp switch. https://japan-itema.com/product/luxman-as-55-speaker-selector-passive-high-definition-audio/
Can anyone comment on its quality and performance?
I want to use it with a Luxman L-509X and with an Air Tight ATM-1s — to switch between both amplifiers and a pair of Harbeth HL5 Plus speakers.
Does the AS-55 have sufficient quality for these two high-quality amplifiers?
Thank you very much for your advice.
Sincerely,
Jeffrey Liu

The problem of using a switcher to select between a tube amp or solid state amp connect to one speaker is most tube amp is not safe to operated without a load and can caused blown output tubes and transformer !! Accident happens if someone forget to turn off the tube amp before switching! A safer way is connect a 150ohm 10watt resistor on the tube amp each output terminals. Or use this design to switch amps on the fly : https://ucarecdn.audiogon.com/d3ee951e-1868-4baf-986b-d1b2f92cb2fe/-/autorotate/yes/ The 3P3T rotary switch must use a shorting / make before break contact style switch like a Grayhill 44A45-03-01-03S, which can switch 100watt@4ohm or 200watt@8ohm. R1 is a dummy load which can be 25 to 50 ohm and rated 25watt or higher will be sufficient. |
