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.

I added some more photos as requested by A’gon member.

Today, I did some more exploring in Canada for the Yamaha NS5000. Canadian dealer will find out if there are any legal reasons why this speaker cannot be imported into the USA. Dealer has no issue getting me the speaker to my home. He will take care of all the paperwork.

GIK Treatments were delayed shipping last week and were only shipped today. So sometime next week will be when I should have them.

List of speakers that I think will now work with acoustic treatments and DSP.

1) Vandersteen Treo CT (heard it but need 1 on 1 demo this time)

2) Vivid Kaya 90 (heard it but only Kaya 45 or Kaya 25 will work in my room. Not really interested in the 25, need 1 on 1 demo this time)

3) Magico A3 (Heard it and liked it)

4) Harbeth SHL5+ (Have not heard it but will call local dealer in 2 weeks)

5) Paradigm Persona 5F (Will hear it again tomorrow with DSP though the Persona 3F is what I would want for the room)

5) Yamaha NS5000 (Have not heard it, but very interested in it, classified as a bookshelf but it really is not).

" I am surprised at how effectively you are able to tune the NS-5000’s bass response with the bungs—Yamaha has obviously put some very serious design effort into ensuring these alignments are truly effective in adjusting the low-frequency response."


6) KEF Reference 1, TAD ME1 (Will work in my room but lack of enthusiasm for them)

My understanding of the sound characteristics of my list from musical-to-detailed sound (left to right): Harbeth, Vandersteen, Yamaha, TAD, Magico, KEF, Paradigm. Some rounding error likely present.
The following items were shipped by GIK today.

This shipment includes the following items:
# Description  |  Qty
244 Bass Trap with FlexRange Technology  | 2
FreeStand Bass Trap |  2
Monster Bass Trap with FlexRange Technology | 4
Monster Bass Trap with FlexRange Technology  | 1
imho, it should sound awesome but you’ll be frustrated that you can’t use them to their full potential.  Its like driving a 600hp car in a 55 zone.

:D
@tobaccoleafpie  Are u referring to ALL of the floor standers on my list or just a specific one?

One way to alleviate the frustration of not being able to drive the office speaker to the max ability is to have an equal or better system downstairs in the rather large space which is a playroom at the moment. That will take some lottery ticket luck and also a bit more time for my toddler to get a bit older. I need to share his playroom with my big rig.

If you do get the Treo's, I don't think you will be 'frustrated' by their performance in your office. The best part is when they can be moved to the larger room, you can get the Vandy subs and be as close to a Quatro at a fraction of the cost(buying used, that is).
