They don't light up once the tubes are warmed up. Where can i find new replacement tubes?** A: The short answer is Google and Ebay...the cool kids replace the tubes with NOS-(New Old Stock) tubes. GE tubes are good. The are many options and prices vary significantly. "They" say that the different tubes bring out different nuances in the music. I have window shopped tubes, but have been using the original tubes to get a base line. If it is DOA, you might want to return it and get a good one, then head down the tube rabbit hole. At this point, you don't know if it's a tube problem or someting else. **Q: The description says that this has subwoofer output, but i am not seeing it in the pictures. does this actually have a sub out?** A: Dear Sir,Thanks for contacting us. According to our colleagues, the QINPU A-6500 does have the subwoofer output. You could connect it via the line out jack.Feel free to contact us if you have any questions or concerns.Kindest RegardsAmyHiFiMAN Customer Service **Q: Can this amp be used as a mono block?** A: There is no provision for bridge-mode thus no, I don't think so. **Q: Does this have more power than the a-6000 mkii? what are the main differences?** A: I have both, and functionally they are identical. The A-6500 has "improved circuitry", but I think you'd be hard pressed to tell the difference. I've had my 6000 since 2013, and it's been solid so far. I use Wharfedale Diamonds and a powered sub, and the power is more than adequate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value for the price considering all that it does so well. *by U***E on November 29, 2015* I recently purchased this amplifier due to its price and it ability to effectively drive both headphones and a pair of bookshelf speakers for near field listening at the desk. I am still in the process of evaluating this, and really haven't explored it's headphone capabilities. However, it is very similar to the previous Qinpu A-6000 MKII amplifier. I think the reviews on that particular unit are very accurate for this model. I will update as I learn more about what this unit is capable of. I currently have it paired with a pair of Wharfedale Diamond 10.2 bookshelf speakers, which is drives to very satisfying volumes. I also utilize the Audioquest Dragonfly DAC v 1.2 as a DAC and source from my Lenovo x200 laptop. I have everything connected with Audioquest Evergreen RCA to 3.5 mm jack and Audioquest Type 4 speaker cables with banana plugs.Two Week Update: I just wanted to update a bit more of my review after having this piece of equipment for a little while now. I am probably heading towards the 60 hour listening mark (I work a lot so don't get much time with it during the week). I don't really consider myself an audiophile, but I do have a background in classical music and enjoy quality sound that is reproduced well. This unit is just amazing for a desktop system. It has really opened up quite well (both the amplifier and the 10.2s were brand new and are just now getting broken in). Listening to the London Cast of Phantom of the Opera places the performance right in front of you with ample volume to provide a lifelike performance in your small space (my bedroom). I find myself just stopping to listen to the quality of sound that is produced. Next think I know, I have been listening for three hours. I can say that this unit is well worth its price. I will say that the aluminum housing of the amp will get a LITTLE warm behind the tubes adjacent to the transformer when pushing at higher levels for an extended period. However, nothing so far has been alarmingly warm or compromised sound quality. I would highly recommend this unit for someone just starting out into the arena of mid-fi/hi-fi sound reproduction while on a budget as a great starter piece to build a system around (my entire system with cables was about $,100... not including headphones). I don't feel that you have to compromise on speaker sound quality.I will say though, that I am a bit disappointing with the sound quality that I have gotten out of the unit on my HD 700 headphones. The headphone sound seems a bit too dark and muffled and really takes some of the excitement and life out of the HD 700s. I am curious if rolling the tubes will enhance this fault. However, if I do decide to just listen to the headphones, I am still able to get a very decent sound utilizing the headphone amplifier within the Dragonfly DAC and bypassing the Qinpu for now. I will keep playing with it and let everyone know what I can find out. I will probably start looking into compatible tubes within the near future. I am thinking the same tubes for the A-6000 would be utilized in this amp. However, being new to this, I will have to confirm. If anyone has any comments in this regard, feel free to comment here and let everyone know.One month Update: This unit seems to be breaking in very nicely. I will preface this comment by noting THIS IS A $250 AMP!!! It isn't perfect but it is outstanding for that price point. However, I have noticed that if I am listening to something with very complex orchestrations with detail in the bass, it isn't the most perfect at resolving all of the detail in my setup. This may improve by rolling the tubes as it seems to based on the comments on the A-6000. Would I recommend this amp? ABSOLUTELY!!! At $250 it is a steal. Would I buy it again? YES! Now I think it may be time to roll the tubes and see how that helps things.Tube Rolling: I just put in a pair of GE5670W tubes. Definitely a noticeable improvement. Improved gain, detail and more detailed sound. Definitely well worth the $10 spent on tubes. I may investigate the merits of better tubes in the future. ### ⭐⭐⭐⭐ It's a very good amp for the price *by P***A on June 1, 2016* It's a very good amp for the price. If you like the look, go for it. Sound will not disappoint! ### ⭐⭐⭐ Keep looking. *by S***A on February 1, 2016* This amp is now a paper weight. The sound quality was fantastic considering the price point, when it worked. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/20354961-a-6500-desktop-vacuum-tube-hi-fi-amplifier](https://www.desertcart.gr/products/20354961-a-6500-desktop-vacuum-tube-hi-fi-amplifier) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-07*
