    Cayin CS-55A

    • The CS-55A is the most recent advancement in tube amplifier technology created by Cayin. This state-of-the-art machine boasts forty watts per channel by using 4 KT88 tubes in Class AB ultra-linear push pull amplification. The CS-55A consists of four pairs of input: one Phono, a USB port, and two line inputs giving a wide range of options for any listener.
    • The CS-55A comprises of a fully anodized aluminum front, a vented chassis with a gorgeous finish, the finest hand-made point-to-point wiring, and a soft-start circuit to enhance the life of the toroidal power transformer and output transformers. Combined with audio grade capacitors, carbon film resistors, and ceramic tube sockets, this is one amplifier every audiophile should have in his/her collection. Speaker output impedance can be swapped between 4 ohms and 8 ohms. Similarly to the A-88T, the CS-55A comes with a handy remote control.
    • Transform your music system! Extraordinary value and performance best describes the Cayin Audio CS55A Integrated amplifier. As the centre piece of any system, the unit is at home with both analogue or digital formats. CS-55A includes a built in MM phono section to accommodate turntables and a built-in high resolution DAC for use with computers. Via the 2.0 USB input, the DAC is capable of covering digital audio signals up to 32bit | 384kHz. This combination of a high end DAC and tubes makes for a rich and detailed soundstage.
    • The output stage can be switched between Triode and Ultra Linear mode and either KT88 or EL34 tubes can be used for the maximum amount of flexibility. A headphone jack on the front completes the unit and makes this one of the most versatile and compelling products on the market for 2016.

    AMAZING!!

    This amp is amazing, even with the stock tubes. Beautiful open sound stage. Separation like I have never heard. I have this paired with klipsch 150m speakers and they sound like I am in the room with the music. The speakers completely disappear. I have just bought some RP-6000f to replace them as this amp has way more power than my last and I want to drive larger speakers.

    I rolled all the tubes to Matched Genalex gold lions and it was well worth the cost of the tubes. The stock tubes are great, but the Genalex bring this amp to a whole other level of Sonic Nirvana. The separation is so clear I can hear the saliva in the mouth of the singers.

    The DAC worked plug and play with my volumio raspberry pi and when using Tidal (I hate to say this) I can barely hear the difference between there masters and my records . Sometimes I prefer there master to the record due to no surface noise.

    The phono preamp blows my Pro-Ject Tube Box S2 out of the water. probably due to the new tubes. This is a fantastic integrated amp for the money. Go buy a Mcintosh for $2,500 and see what it gets you.

    I have owned plenty of amps in my days but nothing in this price point is going to touch this amp.

    Fantastic!

    Purchased the Cayin CS-55A to replace my beloved Rogue Audio Sphinx V3. I recently purchased B&W 705 S2’s and felt I needed an amplifier upgrade and decided to go all tube. I wasn’t expecting such an upgrade. The amp looks and sounds fantastic. The phono stage is really good. The phono stage in the Rogue was good and it’s at least it’s equal, if not better. I really don’t feel the need to upgrade to an external phono stage. Delivery only took 5 days from China. Can’t ask for much better. Highly recommended.

    Cayin CS-55A

    I bought the CS-55A as an upgrade from a Yaqin MS-30L  EL34-based amp that I bought last year.  The CS-55A has exceeded my expectations in every way.  The workmanship and components are outstanding for an integrated amp at this price; and while I had liked my prior amp, it was immediately clear that the CS-55A was a significant improvement.  It can use either KT88/6550 or EL34/6CA7 tubes, and the EL34s it came with - which were likely made by Shuguang - were only "so-so."  But after I replaced them with the Tung-Sol EL34B tubes from my old amp the sound went to a whole new level.  Great clarity throughout the audio spectrum and across genres, but with wonderful EL34 midrange richness.  I've also tried Tung-Sol 6550 tubes in it, and the amp was incredibly clear and powerful sounding with those.  I had expected this Cayin to be the "next step" for me in a progression of more expensive amp purchases, but given how great it sounds I see no reason to look further.  I also want to add the MusicTeck's support staff were great.  They responded to all of my pre- and post-purchase messages quickly, they actually provided answers that were specific and that answered my questions, and they were really pleasant to deal with.  No regrets at all about buying this amp, or about buying it from MusicTeck.

    Excellent tube amplifer!

    Cayin CS-55A was such an upgrade to my system that I had to buy a new turntable and speakers to utilize its capabilities. It has exceeded my expectations and can highly recommend it. It even comes with a DAC and phono preamp!
