    Opera Consonance Cyber 30 Headphone/Intergrated Amplifier

    How much are they selling these tubes in Hong Kong? I just did a quick search, and it is only available in the U.S. through eBay from a seller in Hong Kong, but he wants US$200 for a pair shipped!

    Opera Consonance Cyber 30 Headphone/Intergrated Amplifier

    Haven't visited these forums for a long time. My headphone rigs are just collecting dust in the study room these days. This amp was my first experience with 2A3 tube. It takes some getting used to as it sounds very different than any other tubes. Some people likes the sound, some don't. I've...

    Any body using or used Consonance Cyber 20?

    Skullguise, With your Cyber 30, do you hear a low background hum? I also have a Cyber 30. Besides the stock Chinese tubes, I also have a pair of Sovtek 2A3s, and a pair of NOS RCAs. The hum is present with all three sets of tubes. I played around with the biasing. it lowers the hum, but does...

    Any body using or used Consonance Cyber 20?

    Haven't been hanging out here for a long time. I've been playing with my main rig most of the time these days. I come here once in a while to see what's going on in the world of headphones. This amp had garnered quite a bit of discussion a few years ago after it was reviewed on Positive...

    Has amp making evolved?

    I've been away from (participating in) this forum for about 2 years. Recently just came back to see what's going on. One observation I have is there seem to be a convergence, or more focus, or popularity, or consensus, or whatever you want to call it on products from several major manufacturers...

    Japan Meet?

    I just visited Japan between Christmas and New Year! Got a chance to visit some hi-fi stores while I was in Tokyo. I was mainly looking for a cartridge for my turntable. I would have loved to meet some of the Japanese head-fiers the next time I travel to Japan!

    Dumb question.....tubes...

    With tube gears, you usually don't want to turn them on and off too often. The act of turning them on and off actually will shorten the life. And tubes need time to warm up to sound good. So it's always a decision whether to leave it on of turn it off when you are taking a break between...

    Quote: Originally Posted by Zanth I'd never buy an amp that couldn't do all forms of music equally well. When you find one let me know. I like to buy one. All equipment/technology have tradeoffs. Especially at the lower price ranges. Tubes are not perfect, they introduce some...

    Airline Security

    It varies from airport to airport. I travel for work almost every week. I put my portable rig in a digital camera bag, with iAudio X5 in one pocket, amp in another pocket, connected by a homemade dock cable that extends out of one pocket and goes into another. Also a pair of Ety headphones (more...

    For what types of music are tube amps good for?

    I think it is a matter of taste and preference. In general, SS is more dynamic and has better bass control. Not necessary more bass, but tighter bass. Tubes give you a more organic, romantic sound especially in the midrange. If you are starting out and you listen mostly to rock and metal, I...

    Opera Audio Cyber 30

    I have had this amp for quite a while. Although it was enjoyable listening to it driving a pair of Sennheiser HD650 w/ Zu Mobius cable, it never really "touched" my heart. The amp came with a pair of EH Gold 2A3s. After doing some research on Tube Asylum, I purchased a pair of Sovtek 2A3s. They...

    5.1 stereo speakers on a gaming

    I am assuming that these are not self-powered speakers? (meaning that they don't have amplifiers built into them) If so, you will need to get a surround sound receiver which will take the input signal from your console (usually through a pair of RCA interconnects) and process the signal and send...

    Need some tubes recomendations for the Rudistor RP5.1

    Thanks Edisonwu, that was the information I was trying to look for. So as I had mentioned earlier, if the amp is designed with 6DJ8/ECC88, you can sub with 6922/E88CC and 7308/E188CC. You might want to pass the info to Rudi and see how he responds and post here as I would like to know the...
