The volume control has a cheap clicker wheel that's meant to give the volume control the feel of a more expensive wire wound resistor but it's just a cheap volume pot made by ALPS. The input selector and tape source switches bend back and forth on the pcb when you turn them. The input preamp and phono stage are using IC op amp stages which are nothing to write home about. So you see this amp isn't amazing yet has a high price tag

@ usbcable - 28.05.17 - 08:09pm I recently repaired a Cyrus Two amplifier.. In it's day it probably cost over 700 but the build quality really isn't great. The compactness of the components causes it to hum when the volume is turned up with no signal. The headphone socket is wired with a resistor in the ground instead of one in each left/right channel which affects channel separation when headphone listening. Thin plastic pegs hold the power switch push rod and I had to glue and reinforce these as they were broken.... What version did you get as their was 3 revisions of the Cyrus two . the last one with the clicky on off switch being the best. Most Cyrus 2 amps are very old and will need re caping . schematic s are avalible online and a full set of caps will cost about 20 pounds . its well worth doing.sounds like your one does as it should not hum at all. |

Thee first version of the Cyrus 2 was plastic . the later models are cast magnesium alloy and are extremely heavy . they still outperform most modern amplifiers costing up to 1500 pounds .

The case is all metal so I'm guessing a version 2. Did they change the position of the power switch in the later models then. That's a really bad design in the one I have.

No the position is the same . I can't believe you think its poor build quality they are built like tanks . does your switch push in and out ?.

Yes the switch is just a lever that pushes in and out but there's a plastic rod that has cams on each end and rotates as you press the power switch. This operates the actual power switch which is in the lower center behind the front panel. The plastic rod is only held in by small red plastic clips which broke on the one I had.

More modern amps have more room inside and shield the pre amp by putting the power amps heatsink down the middle or something similar to stop interference. The transformer is very close to all the circuitry in the Cyrus 2 and there isn't any shielding to speak of.

All my cyrus amps over the years have been exellent with no feedback at all . im guessing you have one that needs re caping like i said . The design has changed very little in 30 years as it is a classic design ,it doesnt need to be large the transformer used has its own internal shielding and these amps are world renowned for there exellence . modern amps under 1500 pounds are built like crap with very little inside and poor quality internal parts .

One thing they do need is quality speakers and cables to get the best from them ,same as any quality amp . If you pair them with cheap speakers and cheap cables you wont here the best from it . You dont need to spend a fortune but good speaker wire and rca cables do make a big difference . I use cambridge audio pacific rca cables and QED silver anniversary speaker cable
