Big speakers in small room at moderate volume levels


My office is 11’W x 10’L x 9’H and is where I can listen to music for the next few years. I have a toddler and, for now, he has commanded the big spaces in the rest of the house. I have auditioned the Magico A3 and wanted to buy it but that was before I was relegated to the smallish office (I was expecting to move to a bigger room). I have removed the closet doors in this office room. The removal of the closet door gives me another 4 feet of depth to this room, though for only 1/2 width of the room. I can sit unobstructed 8 feet away from the speakers before I hit the area where the closet ends (so near field listening).

I currently I have KEF LS50 with Peachtree Nova 150. It is good and I can listen for the whole day without fatigue. I listen to FM, digital files on ROON, and my Sony SCD-1 SACD player. I want a bigger sound so I am looking at bigger speakers. I also do not want to use a sub since I am not a fan. I will also upgrade the NOVA 150 to the NOVA 500 in Spring 2019 and use with the LS50’s in a bedroom.

I came to the conclusion that my tastes would be best served by one of KEF Reference 1 or Magico A3. I was thinking that I would use the Lyngdorf 3400 in this room but I am having seconds thoughts on this now (some A’gon comments that it maybe a little dry). I am interested in solid state AB units like the Hegel H590 and Mark Levinson 585 to drive the speakers. I have heard the ML 585 and it is a fatigue free sounding unit that was a joy to listen to. I have not heard the Hegel H590 yet (but have heard other Hegels with KEF) and I am in the process of getting an audition of the H590. I have also discounted the class AB Micromega M-One 150 (with MARS room correction) because I do not want a cooling fan blowing in the room.

I must mention that I do not listen that loud when I am working and when I am working very late at night the volume is very low. The Mark Levinson and A3 combo was very good at low volumes during my demo but that was in the dealers perfect large room.

1) Am I making a mistake foregoing room correction with the 2 integrateds I am considering? Should I go with the Lyngdorf and A3 or KEF Ref 1, though I have never heard the Lyngdorf?

2) Will the Magico A3 work in this small room at moderate volumes WITHOUT room correction or will I subject myself to headaches and fatigue?

I am going to ask the dealer selling the A3’s this question when I am ready to buy but i wanted to ask on A’gon first to get some feedback. I doubt I could get the A3’s into my room for a trial but I have not asked the dealer yet.

I think (not 100% sure) the KEF Reference 1 with a non room correcting amp should work in my office space but I would prefer to buy the Magico A3 for the office. I have plans to buy another KEF model once my kid is a bit older and I can kick him out of the big room.

@tomic601 I took another look at the "Who has Luv for the Lyngdorf 2170 and is thinking about the 3400." thread. I read it from beginning to end. I actually posted some questions into that thread a few months ago.  

https://forum.audiogon.com/discussions/who-has-luv-for-the-lyngdorf-2170-and-is-thinking-about-the-3...

It was a good read and I did a deep dive into the posters eventual systems and other thread comments (spent about 4 hours). It also got me feeling optimistic again on the bigger floor-stander for my room. My take away as pertaining to my situation:

1) Having a treated room prior to apply Room Perfect DSP is not a bad thing and will cause Room Perfect to have to do less work. Your speakers can have the burden of reproducing certain freq's removed by getting rid of the room treatments and having the Room Perfect deal with it. However, I would not do this and plan on keeping my acoustic treatments. Let the speaker work.

2) The amplification stage after the DSP can be variable. You can use the Class D as built-in on the amp. Or, you can buy a separate amp and use the RCA or XLR pre-amp out to an external amp. One user on YouTube mentioned he has a tube amp, a SS class AB amp, and the default internal Class D amp hooked up. He uses solid state when he wants background and the tube when he is focused on the music. Not saying the tubes are better than the default it was just this posters preference. A lot of A'gon posters love the sound of the Lyngdorf by itself. I have not yet contacted your friend about the Lyngdorf and Treo CT.  I want to listen to the Lyngdorf first.

3) The Lyngdorf system sounds best with digital files. There is an upgraded analog input card that I would need to get and this does a A-2-D conversion of the signal. My listening of my analog sources are not that high. One CD a day on my modded Sony SCD-1 (a fun sound for me) and some KCRW.com FM radio (if they are not playing AutoTune garbage). Most of my listening is Tidal/ROON which the Lyngdorf is optimized for. It also has an Ethernet DAC streaming input, though the USB is supposedly still better sounding. My Sonare microRendu needs to follow my KEF  LS50's to whatever room it goes to so the Ethernet input can save me a few dollars until I get another Ethernet-2-USB device.

3) The digital processing of the digital files is done by a Texas Instruments chip. I do not think this is a DAC chip, though in reality I do not care nor do I need to understand all the details. It is supposed to be lossless or bit perfect or something of that nature.

4) The volume control is excellent and the volume comes from a silent background at all levels. I heard the beauty of the silent background with my old Benchmark AHB2 amp ($3K)

5) Dealer states that a floor stander the size of a Magico A3  or Treo CT can work with DSP in my room. I am skeptical but hope to be proven wrong.

6) I need to go listen to this amp this week at a local shop. I will make 2 trips down to the dealer. If the first trip shows me a general sound that I like without the DSP, I will ask to demo this unit again using DSP with something that approaches what I am looking to get. It takes time to dial in the DSP with the microphone setup.

As I begin this journey back into audio I am starting to become a bit of an audio geek. I have some interest (if / when funds permit) to try a tube amp and class A amp. Buy and sell gear just to try like a lot of you guys here do. A lower power requirement on the speaker will give me more options. Another plus for the Treo CT over the Magico A3. A few amps that I am interested in are the following:

- Benchmark AHB2 (buy this back, sold it to make an investment)
- BAT tube amp (had an old SS BAT VK-42SE preamp and loved it)
- Krell XD amp (want to demo this)
- Mark Levinson amplification 
- Pass Labs
- CODA pure class A amp
- and whatever else comes along

With the Lyngdorf in the pre-amplification stage, with or without DSP turned on, I believe I would have a framework to do this. You are not tied to any particular amplification if this is the intended nature for the pre-amp outputs. I will confirm this with my dealer visit later this week and also try the pre-amp out to maybe a Simaudio amp they have.

@james63  I forgot to mention that in my downstairs space. I have 30 foot long wall, when the adjacent family room is accounted for. So the science for the acoustics in that room  should say it is an excellent space. That space will get a family friendly big rig system. Just waiting on my lottery ticket for that one.

BTW - for anyone wondering why I am writing so much verbiage. It is a way for me to remember the things I am finding along the way. I have re-read this thread a few times to focus my thinking.
yyzsantabarbara,

The vivids look nice but I always ignored them due to price. I have the opposite issue as you with a 27’x25’x7.5’ deticated room (real estate is cheap in Ohio). I have the setup off center and a carefully selected seating position to help with the square room issue.

Low bass seems fine in my room but I struggle to get good mid bass impact and really need big speakers and that gets pricy (good and big…). With my duel subs I have a good bit of flexibility on speaker choice but the A3 is probably the smallest speaker I would go with.

For what it is worth when I was remodeling I put a pair of B&W 803s (not D) in a 12’x11’x8’ room and was really surprised that it sounded fine. I am sure the bass was lumpy but I remember thinking it was pretty enjoyable honestly with great impact in the mid bass. However I did not know much back then and it was my first “real” set of speakers which I grew to hate lol (too harsh).
I would say this popular thread benefits from your extensive writing on the learning / personal journey of discovery while you solve some unique issues with demanding requirements- people are investing in helping you and learning themselves...

to that end i had another reason to read the Lyndorf 3400 manual

it has extensive filters for high Pass as well as frequency response smoothing DSP

you should be able to set a first order filter at 40 HZ or so and fix some room gain issues 
I made a change to the furniture in the room. I got rid of the desk facing the speakers. I can get by with out it. I am also going to remove the ugly 30 year old side table I have near the right speaker. The cable modem and other wires will go to the ground.

Listening to Muddy Waters "Hard Again" sounds much improved now. It sounds like a big desk has been removed from in front of the speakers. A brilliant move on my part.

I must say that at the moment the LS50’s are sounding alight. It would be interesting to try it with better amplification but I am not going to diverge from my plans to do that. I will get the Harbeth SHL5+ for a home demo in 3-4 weeks with my Pearchtree Nova 150. This will show me the character of the Harbeth and also show how a bigger speaker sounds in the acoustically treated room.

I will post photos soon when I install the acoustic treatments that should be in transit to my home.

@James63 I demoed the A3 at Brooks Berdan in Los Angeles area. The room may have been 3/4 your size. That room sounded great with A3 and Mark Levinson gear.

Happy New Year to all.
It may have been said in earlier posts but Lyngdorf 3400 in addition to automatic correction and eq curves also has manual dsp correction. So you are actually able to get whatever sound you like. If you want subs to do the low parts the crossover facility in Lyngdorf amps is very good. A much cheaper but powerful alternative would be the new XTZ edge amp paired with an Antimode 2.0. No crossovers though.
