Really nice tube amplifier, I gave it to my tech to check out before I started using it, he examined it and began burning in the tubes to check to see if it would continue to operate as it should as it breaks in, all went well so he turned it back over to me. I have been playing it nonstop since, I believe tubes need a hundred hours or so of signal to really break them in enough to make a valid evaluation and so far this thing sounds and looks as good as it could, rivaling amplifiers 3X its cost. To me, at this point, this is the deal of the century. Packed in abuse-proof packaging, this baby really is good value for money. Will be seeing how it works over time but my tech assured me it looks to be made of high quality components, all clearly marked and not cheap crap, and said if any problems develop, short of losing a transformer or something, this amp is very repairable but looks to not be needing any work anytime soon. Might try tube rolling especially the first stage tubes, but for now am completely happy with the performance and looks of this beast. Review: EXCELLENT Quality and Sound - Amazing quality and sound. Knobs and switches are super high quality and feel great, especially the volume knob. I use ultra linear mode for fast transient or bass heavy music. I don’t have great ears, but my golden-eared wife says ultra linear mode has better instrument separation while triode mode gels everything together. Tube biasing is super easy to do. I don’t have much need for balanced input though I do have balanced cables so I am using them anyway but I have no clue if it makes any difference. Similar models have a subwoofer output and I almost wish I would have chosen one of them, but I chose the A88 for its looks. It does look amazing in person and is much bigger and heavier than I expected, so do make sure that it will fit in your setup. Another useful feature is the “main in” input which you can use to incorporate this amp into your home theater system. My only two complains are that the VU needles are a little hard to see against the black background, and the knob indicators are also hard to see or feel in low light. Would have been great to have a little notch or something tactile to feel where the knobs are turned to for input selector and volume. Would be great to have a clearer visual cue as well, either a darker marking or better yet an LED that you can see even in the dark. ## Features - Pure Sound, Craftsmanship Masterpiece: The Oilily A88 tube amplifier offers an all-vacuum tube design with handcrafted point-to-point soldering, providing audiophiles with an unparalleled musical experience.

The 3 stars are for the amp itself. While it is beautifully crafted and the quality of workmanship is excellent, the amp just didn’t sound good to me. I had it 11 days and gave the KT88 tubes plenty of time to gently break-in. The sound out of the box was horrible. By day 10 it had gotten much better but still not what I am looking for. Sound stage was nice and wide. The bass was just fine, really good even, but the mids were awful (to my ear anywat). Snare drums sounded like the drummer was hitting a cardboard box instead of a drum. Vocals were sharp and unpleasant. Now before you think it may have been my speakers, I have had my Zu Soul Superflys for 15 years. I have been running a ST-70 clone (joe Curcio upgrades) for the past 10 years and the speakers sounded awesome. Shame on me for selling my ST-70. I fell for a couple of positive on-line reviews of the Oilily A88 MK. At any rate I’ve returned the unit and continue my search for a new amp. I’m tempted to try the Oilily 300B amp but am also considering the Advance Paris A12 Classic. ## Frequently Bought Together - Oilily A88 KT88 X4 Tube Amplifier, 45W+45W Class AB, Vacuum Tube Integrated Amplifierwith Triode & Ultra-Linear Mode, External Bias Adjustment, High-Fidelity Sound for Audiophiles (Black) - Amazon Basics 2 RCA Audio Cable for Amplifier,Active Speakers or Subwoofer with Gold-Plated Plugs, 4 Feet, Black - Micca 14 Gauge Pure Copper Speaker Wire, 6 Feet (2 Meters 6.6ft Actual), 2 Pack Pair, Gold Plated Banana Plugs, Soldered Construction, Slim Design, 245 Strands, for Stereo or Home Theater --- ## 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.sn/products/678655836-oilily-a88mk-kt88-x4-tube-amplifier-45w-45w-class-ab](https://www.desertcart.sn/products/678655836-oilily-a88mk-kt88-x4-tube-amplifier-45w-45w-class-ab) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-06*
