Ive been an audiophile for over 30 years and have owned two-dozen amplifiers over this time. I have to say the Reisong A12 is my favorite of all them, which is saying a lot. This amp can be used as a integrated or power amp (I used it exclusively as a power amp). My A12 is just over a year old, and Im the original owner. Its in like-new condition cosmetically and operationally. I have the original box and all accessories (including the tube cage). If you want a more detailed opinion of the A12, you can read my review on Amazon (look for Top Reviews-Eric L): https://www.amazon.com/BOYUURANGE-Reisong-A12-Stereo-Single-end/dp/B08SWK24QJ/ref=sr_1_1?dib=eyJ2IjoiMSJ9.najtwXqqP4IjPD3V32Qgktlx3prjYs2Nv55Z_qCPLxiDR1NX7ZAdP2mLNLcm5V4v5ci7bhl-96UzdGoqM_B7-cpYxIN7cd0Mrb8Z6FzlKtw.5wdrzbdFyrbNAJZDIbkPDfMgDYA0jfBo2FTDqsWV-oc&dib_tag=se&keywords=reisong+a12&qid=1714239531&sr=8-1&ufe=app_do%3Aamzn1.fos.ac2169a1-b668-44b9-8bd0-5ec63b24bcb5#customerReviewsSome performance features of the A12:* The design is a class A, single ended triode (SET). This is most simple design an amp can use, which results in superior sound quality.* The amp components are wired by hand point to point. This the best way to build an amp for sound quality as opposed to using chips. Point to point wiring isnt used often due to expense.* The A12 has very good parts and build quality, especially at its price point. USA & western equivalents cost twice the price or more.* The A12 is rated for 6 WPC (its about sound quality, not quantity). 6 watts doesnt sound like much but I can tell you from first hand experience its more than enough power so long as your speakers are efficient (90db @ 1meter @ 1watt or higher).* You can literally change the sound of the A12 in the future if you like by simply swapping its tubes, and you dont have to swap them all at once. Further, the A12 is self-biasing, so no need for a volt meter for tube tuning when changed. I love the sound of the A12 as is, so I never bothered with tube swaps (aka: tube rolling).So who should buy the Reisong A12? Someone who values high quality music playback at home (audiophile), and values the tube thing in an amp: Transparency, detail, smoothness, slight warmth, holographic imaging and sound staging. Or perhaps a new audiophile who wants to try tubes for the first time without breaking the bank. The only reason Im selling this amazing amp is to purchase a bigger, badder, variant of it (LoL: 10 WPC). After my experience with the A12, I wont use another music system without tubes somewhere in the component chain. * A Couple Of Item Related To Shipping: Free shipping offer is to any location within the contiguous 48 states only. Shipping to cost to all other locations will be calculated post auction and paid by the buyer. IMPORTANT: I can only ship the amp via UPS Ground on Saturday or Sunday.

Reisong A10 KT88 Tubes Hi-Fi Audio Stereo Tube Amplifier This amp sounds wonderful, upgraded KT88 tubes. I only used once or twice a month. It’s 2 yrs old and in perfect condition. No hums or buzz. Smoke free home. No scratches just a little dust. I have upgraded so I haven’t used it in months. Power cord included. Free shipping within the US.

I purchased it for its looks, to add to my industrial themed home office. Works great but after some time I had a little buzzing in one channel, so I swapped some tubes around and the noise followed the tube. I ordered replacement tubes and the noise was gone. A few months later I got another buzz so I decided to order replacements for all the tubes. Before I got a chance to troubleshoot it my annoyance with maintaining a tube amp overcame me and I found a different solid-state amp I preferred. So, Im confident the hardware is fine on this unit, its just a matter of getting the right tubes in the right place. Im including all the tubes, so you get a total of 12 to work with, or you can use your own instead if you have a preferred type (I purchased replacements at the lower end of the cost spectrum). Includes all original items. I removed the metal Reisong name tag from the front, but it is included if you want to put it back on (just held in place with double stick tape). I used it without the black metal grill, but the unused grill is included, and recommended if youll have the amp out where people might be tempted to touch the hot tubes. Comes in the original packaging, which is very durable since it came from China originally. This is a beautiful, heavy, well-built amp. Search for discussions about it on the web, its well respected. I guess Im just not a tube guy.
