The Tonewinner SW-D4000 is a compelling option for those seeking strong, customizable bass performance with user-friendly digital tuning and solid build quality—all backed by a generous trial and warranty. It shines particularly for home theater setups.
pre-amp has now settled into my system well...thanks to the summit power amp.L still have my gripes about the lack of tone controls,but given its current sound I can live with it.
I don't know how to describe my experience with this amp. a few days ago we had a family gathering and it was all the talk.It looks good in my rack and sounds even better. I'll be ordering a second one soon,before they're all gone!!!
Powerhouse media player that actually performs as advertised.
Also excellent customer service from SUMMITHIFI when there were software issues.
Summit hifi was very helpful in the process, very friendly,knowledgeable all around good experience
This amp does everything you ask it to. It provides complete satisfaction in every way. Summit made it easy, which is appreciated.
It was a superb player it played everything that my mom wanted, however the home theater 5.0 didn’t read all of my movie files. There’s certain movie files that they didn’t have the posters in their database but overall I was super impressed with the quality of the player itself
I saw the good reviews and decided to give this amp a shot. It really livened my sound. The speed of the delivery was impressive. It only took two days.
At this price it’s a steal! You’re getting a lot more value for a lot less! Couldn’t be happier!
Running the at-500 and 2 of these running my 7.3.6 theatre, going from using Yamahas advantage flag ship receiver. at low volume they don’t loose clarity or sharpness like the Yamaha would at low volume, the SQ is steady across the entire volume range, I was Leary of a Chinese brand I never heard of but these amps sound like my old emotiva but about 15% better all around, great amps for home theatre use for sure, very happy. And I’ve never had the level of customer service or support like I’ve got from Amir, he’s definitely a top notch guy! I wouldn’t hesitate to buy anything from summit hifi.
Awesome experience from start to finish. Excellent customer service by Amir. Fast shipping, great product, A++
I am still trying combinations of hook-ups. And I have some issues with a defective remote. Aamir is trying to help resolve the remote problem
Been playing this game long enough to know there’s no perfect piece of gear, but the AD8300 is a great performer and excellent value for the money. A single chassis that now replaces three previously used, and more power on even the lower powered channels than previously used.
Dead quiet and surprisingly inconspicuous in the equipment rack, and I particularly like lack of fancy and distracting displays that some folks can’t seen to live without.

I contacted Amir to inquire about the Tonewinner SW-D9000 18" subwoofer. He was very helpful, spending considerable time answering all my questions in detail. Based on his guidance, I decided to purchase two D9000s for my home theatre, which measures 12’ wide, 18’6” long, and 7’6” high. Amir’s service was outstanding. Delivery was prompt and he provided hands-on setup assistance. It was an absolute pleasure dealing with him and I would not hesitate to give him my highest recommendation.
The subwoofers arrived very well-packaged and in flawless condition. Given their size and weight, we unpacked them in the garage before moving them into the house. Getting them down to the basement was a challenge and definitely required at least two people. Setup, however, was straightforward, and the Tonewinner app proved to be intuitive and reliable.
I tested the D9000s with several movie clips featuring intense low-frequency effects. The results were nothing short of spectacular; the bass was deep, powerful, and effortless. Music with heavy bass lines was equally impressive, delivering tight, controlled, and impactful low end. My only concern was the basement walls rattling under the sheer output. I owned many top-brand subwoofers in the past, including companies like Paradigm, SVS, and Funk Audio, and in my opinion the D9000s rate right up there with the best at a fraction of the cost.
I placed a late night order after a lot of deliberation. Aamir reached out personally to confirm the Eversolo A10+F10 would meet my needs and discuss shipping timing, etc. I couldn’t be happier with my first order from Summit HiFi and will absolutely be back.
"Big thanks to Aamir for his
support!
And if you want to see what a real
man truly looks like?
Look at Aamir.
As for the D6000?
In simple words: it's an absolute beast for an outstanding price!"
Really enjoying this sub! Nice and deep, surprisingly faster musically than I expected. Thumbs up!
Except for the unaccounted delay in Fedex shippings, things went fine. The device is up and running fine, and I installed two 26tb disks for storage.
I really want to like this unit but I am experiencing issues with an inconsistent soundstage that goes from extensive (wide) to where all sound comes from dead center. Also getting hiss/static on ARC/HDMI input that can't be corrected by cable swapping or changing power supply. Might be a defective unit, in which case I will update my review in future. But for now it's essentially unusable.
Just finished integrating the DMP-A10 into my two-channel rig, and it’s quickly become the control center I didn’t know I needed. It sits at the heart of a system that includes McIntosh C52 and MC611s, Talon Firebirds, dual REL subs, Magnepan Tympani IVa, and an MC462 — all powered and sequenced cleanly with advanced rack-level AC control. Having the DMP-A10 in place doesn’t just simplify signal flow — it makes everything feel more precise.
Notable wins from the install:
- Sub integration is leagues ahead of anything I’ve used before. Dual outputs with adjustable gain, delay, and crossover made blending RELs and Tympanis far easier.
- Room correction via REW worked seamlessly. I was able to import PEQs and tune crossover handoffs with surgical clarity. The DMP’s DSP tools are robust and don’t mess with tone — just refine it.
- Noise floor is impressively low, even compared to standalone DACs I’ve tested. A/B’d it into McIntosh preamp direct vs bypass and both paths remained dead quiet, with stunning dynamic integrity.
- The interface is snappy, the trigger sequencing flawless, and SSD access smooth. I’m running local files, TIDAL Connect, and Roon — no hiccups yet.
There’s a lot of high-end gear in this rack, and I’ve spent serious time optimizing it. The A10 didn’t just earn its place — it elevated the whole experience. If anyone’s curious about REW graphs or PEQ settings with Tympani panels and RELs, I’m happy to share.
I absolutely love this sub in my stereo listening setup, it shakes the room to it's core and hits the low frequencies that I'm looking for, all while remaining composed, clean and musical. I would easily buy it again if I had to.
Aamir at Summit Hi-Fi is fantastic to deal with and easily offers some of the best customer service experience in the business, and excellent products at a great price. You can tell that he’s passionate about what he does, and I will most definitely be coming back here in the future. I highly recommend Summit Hi-Fi to anyone looking for anything hi-fi. Thank you!
