Solid performance and features, no fluff

ToneWinner sets a new bar for value and performance that rival the big boys at a fraction of the price. Works great with Dolby Atmos (TrueHD and MAT), DTS-X, Dolby TrueHD, DTS-MA, etc.

Remote is basic in construction but checks a lot of boxes the big brands are missing - dedicated buttons to trim center channel, surrounds, heights, subwoofer. For those of us that love to tinker and dial their channels in, this is a HUGE plus. Dedicated buttons means no more digging through on-screen menus or apps to get your system just right.

The same can be said for selecting the upmixer / stereo / direct modes of your choice - no more clicking MOVIE or MUSIC to cycle through all the modes to get the one you want - dedicated buttons to Direct, Dolby, DTS, Stereo.

HDMI switching is a breeze. A tad bit slower than the big box brands, but no more or less reliable. On the odd time it fails to connect, cycling inputs resolves the signal.

Integrates well into Logitech Harmony, but you have to teach / learn the codes. Currently missing are discreet power on/off codes, but those
may come in the future?

Thanks for your help Aamir - a consummate professional as always!

This processor has a lot of cool features for the price.

My setup is 9.2.4 and the Atmos and DTS-X quality blows me away!

Event the "Multi-channel" surround setting does a great job of sending sound to all speakers, especially when watching sports (hello, Formula One !). It even sounds better than both DTS's and Dolby's upmixers depending on the source.

The remote is great, with useful buttons, but I do wish it were backlit.

The AT-300 also looks great, in a subdued kind of way and feels very solid.

There are tons of customizing options but, like reported by many (and I do mean many) forum posts, the auto-calibration is not very good compared to Audyssey or Dirac.

Sure, the on-screen display looks a bit low-end (maybe a future firmware update will give it a more high-end look...) and the HDMI switching is sub-par: having to wait more than 15 seconds when I switch from an NVIDIA Shield to a Zidoo player is very close to unacceptable (I'm using 1.8 meters long and 8K certified cables), but once "locked" on the signal, visual quality is stunning.

The Bluetooth receiver sounds like total crap... but I wish it could also send Bluetooth to my headphones for "quiet" movie watching.

Other than those few negatives, this is a great pre-amp.

Wish list: an upgrade to the Dolby upmixer to take advantage of the front wide channels and, why not, DTS-X pro, since the chips in the AT-300 are apparently able to handle it.

Finally, Aamir from Summit Hi-Fi went out of his way to please me when I ordered: shipping was fast, price was amazing and he does seem to place customer service at the top of the list.

I'm more than satisfied with my purchase. Highly recommended to audio hobbyist but may be a bit to eccentric for the average user.

Why has the price inflated?

Curious why the price inflation

AT-300 does the job.

First off, a huge thanks to Ammir at Summit HiFi. Because of our proximity, he was able to get this processor to me in under 24 hours. I've never seen that kind of turnover before. Just outstanding.
As far as the actual unit, I'm still testing it out, But thanks to the latest firmware, a lot of the unit's larger issues are ironed out. I'm still seeing occasional glitches where the unit's HDMI handshake takes awhile. Also my amplifier has just turned off as its loses the 5V trigger out connect. These are issues I'm willing to live with for the low cost of this unit. The sound quality is actually excellent. Detailed and large sound spaces. Improved clarity over my Emotiva MC-700. Excellent bass where it needs to be. I was able to dial it in a little using the included directional mic and the improvement was very noticeable against the stock settings. I'm really excited by having Dolby Atmos now, and I can tell an obvious improvement. The form factor/size of this unit is perfect for me, as well. As i get used to it, it's just sounding better every day. I'm still impressed by this little unit. I took 1 star off, because of the occasional glitches I've seen. I'm not spending $5K on a better unit though. I'm good.

Tone winner AT-300 Processor TOP NOTCH

First off, thanks to Amir and Summit HIFI for there help and getting this processor delivered to me in a timely manner. It arrived on December 23rd
but I didn't have time to get it all hooked until a few days ago. Let me tell you, the AT-300 SOUNDS FANTASIC. The audio is very detailed and the
separation is excellent. Sounds great in home theatre and 2 channel, very immersive ATMOS and DTSX. In 2channel the music seems to be coming from different parts
of the room like it's 3 dimensional. My room has been professionally sound proofed and acoustically treated so I have not used any of the room calibration as of yet. Very happy with the processor and it's performance is beyond it's price point. HIGHLY RECOMMENDED!
