Room Correction Required


I have to part with my Supernait 3. I have enjoyed it as much as possible in a room where I have a 7bB at 80hz hole at my listening position. It starts at about 125hz, bottoms out at 80hz, comes back up around 60hz before dropping into a black hole at 50hz. On top of that I have a serious peak (12dB) at 40-30hz. It makes for an odd musical experience. Obviously this is not the fault of the Naim. My previous unit did the same thing but I was wishing that the Naim would power through it. I also replaced my speakers in the same vain hope. Wishing vs. science..... oops. When I get out of the null zone the tonality is great but I can't be seated that far out of the space without looking really dumb or antisocial. Also the sound stage is wrecked when I get out there.

I have lived in this home for a year and a half. The issue was worse before I pivoted the room arrangement 90 degrees. My partner is an artist and designer, so I have blown all my rearranging capitol for the next 10 years (her words not mine). We looked at adding room treatments and perused the currently available options which look like church or hospital decor; SO NOT HAPPENING (her words again but I have to agree- yuck).

As a result, I need an integrated with room correction. Yes, I'm sticking with an integrated because I want a minimal gear set.

-TT via Gold Note PH-10/PSU10, outputs either balanced or single end.
-Prefer built in streaming to lose another couple boxes but it's not a deal killer. Current DAC outputs balanced or single end.
-Powering MA Silver 500 7G, not looking to change these.
-Single Revel B112v2 Subwoofer (not currently in use as the 500's are already peaking in the same range)
-TV, currently input optical to the DAC.

The top contenders are:
Anthem STR (no streaming)
NAD M33
Lyngdorf TDAI 1120 (the 3400 is not budget friendly).
Yamaha RN-2000a

So if anyone has experience with these units I'd like to hear about it. Also, I know it's going to happen and god bless you all; someone is going to tell to reposition my speakers (been done), stuff the ports (been done) get room treatments (ummmmmm nope?) and buy Luxman, Sudgen or something else because of __________ (fill in the blank). That's fine and I appreciate the advise but I don't see any of that happening in this room anytime soon under the current design driven regimen I live under.

Thank you all for taking a look!

Also, consider maybe all you need is EQ, not room correction.  In that case Roon will help you just fine

If it weren’t for the turntable that would be correct 

I agree with above. I need a system which will give me some good bass management as opposed to no management at all.

I have the STR. Couldn't be more happier with it.

The STR is first on my list for many reasons. I think ARC is a mature and tested system that allows curve modification. I think Anthem is a good company. I really don’t need a sub with the MA Silver 500 7g but if I wanted to put it in mix ARC allows a greater degree of bass management than the M33. The issue with the Lyngdorf is the low power output and the fact that I’m moving from the Naim Supernait 3- I’m concerned that the 1120 is a step backward in sound quality. Other than the issues with my room the Supernait sounds fantastic, better than had hoped. It drives my speakers with ease and great control. I’m spoiled in that regard.

Have you  read this thread? Maybe an equalizer would really help.https://forum.audiogon.com/discussions/equalizer-in-a-hi-fi-system
 

Great idea! I’d be all over it if the Supernait had a balanced input but since it doesn’t I’d be limited to one source. Also it sort of negates the lower box count objective. I could conceivably bypass the XLR issue by making up an XLR to DIN cable set but do I really want to do that? I’m thinking not really.

Do you have Roon? You can do room correction with Roon  by just acquiring a microphone to measure and using Room Eq Wizard freeware. I just did it with one of my rooms with excellent results. One room down, 3 to go.
 

I have Roon but it doesn’t help with the turntable

I see quite a few 3400’s in Europe for reasonable money but the are all from sites I don’t know and advertised in languages I don’t speak. All of that is a bit daunting.

He Loves loves the Nait 3. But also loves the 1120 and the latter sells like hot-cakes.

I was on verge of pulling the trigger on the 1120 but I was concerned about driving my MA floor standers. Sensitivity is 90.5db so is would work theoretically but…..

The 3400 would have been my 1st choice but the prices are a bit high right now. Maybe in the future.

 

 

The ARC stuff is very cool and can make a difference, but it’s not going to help your 80hz problem. That’s a placement or room treatment issue and I know that’s a tough one for you. So ARC will make things sound better but not exactly what you’re dealing with.

I guess I’ll find out, I ordered the STR Integrated. It should be here next week and the truth will be known. 🤞🏻

Roon DSP won’t work with Vinyl or a TV input. I used it to handle my streaming input and it works well. I need a whole system solution however. I’m counting down for STR arrival.

The STR Integrated has been in place for 24 hours now and I have some observations. First off, it’s big. It’s also black but not as black as the Supernait which may be the most absurdly black object I’ve ever seen. The STR speaker connections are on the correct sides, unlike the Naim, whose sole redeeming quality is highly engaging sound reproduction, which causes one to forget the weird  things about a Naim product.

As to the STR non-DSP/room corrected sound quality, I was prepared for a letdown. What I was not prepared for was the similarity between the STR and the Supernait 3. First is the transient attack which is excellent on both and one of the qualities I was worried about giving up. No worries on that score, the STR sounds nimble with percussion and outstanding with piano. The STR may best the Naim on sustains but since I don’t have them both here I can’t be sure, I certainly don’t feel like I lost anything in that regard. One thing the STR brings to the table is gobs of power and you can hear it.

All in all, in a non- corrected state, I can’t say I lost anything with the STR. I bought it for the room correction but even without that feature activated, for my equipment in my room, it’s a much better match. 
 

The 30-40hz peak and the 70 to 90hz null are still there so tomorrow is ARC day. I’ll update after I bumble through that.

I’m betting that since the mid bass null is not too severe, it will be bettered or cured. The null at 50hz is a solid black hole- I don’t expect any improvement there.

I’m absolutely pleased with the results of the STR Integrated using ARC. The first run immediately eliminated the 30-40hz peak (prior to correction it really sounded like a 14 year old had gotten at the subwoofer controls). Additionally, via the graphic display of the ARC system I discovered that the 80hz centered null was a product of the right speaker room interaction only. I never ran REW on the individual speakers, all of which is beside the point, because the corrected curve fixed it.

With the low end fixed I found the the high was flat and lacked the sparkling dynamics that had impressed me from the start. The Sterophile review mentioned the same effect so I borrowed the remedy from the same article, which was to limit the upper end of the correction curve to 500hz and presto! All the good and none of the bad. I’ll probably lower that some more.

I found you can edit the curves for different sources by saving and assigning different profiles. This is great because my TT via the Gold Note PH-10 can be a touch bass heavy while the output from the TV TOSLink is what you’d expect- not the first word in dynamics. All of these things can be adjusted on the fly and the results are great.

The next phase was to reintegrate the subwoofer into the system although I thought I could live happily without it. Mostly I was just curious about the effect. The effect is very good, the bass is tighter still. Double bass work in jazz just shines with realism.

I also found I can listen at lower volume levels and still get a great immersive listening experience.

Overall I’m really impressed. I’m easily able to ignore the hugeness of the STR integrated in exchange for its excellent sound quality. On a 1-10 scale I give it 20.
