Lyngdorf 3400 flexibility vs 1120

i liked the 1120 when i tried it, upgraded to the 3400 as i am running magnepans and wanted the additional headroom - it is a terrific piece, well built, excellent sound

i don't listen the headphones

the room perfect feature is tremendous, what an impact on sound of speakers in room

for phono i would go with an outboard phono stage anyways

Suggest you ask @brownsfan 

@bob52r I am a Lyngdorf fan.  I own a 2170 which has made my living room system more than adequate in a room with miserable acoustics.  I've helped 2 of my children assemble 2170 based systems in rooms that are less than ideal.  The 2170, and I presume the 3400 as well, can be an ideal solution where one is not able to utilize extensive room treatments.

In your case, I might well go in a different direction and assemble the best headphone system I can, unless your stay in an apartment will be very short term and you are pretty certain about what kind of music room you will have long term.   

If that won't work for you, then going with one of the Lyngdorf integrateds with Room Perfect might make sense.  I cant comment on the quality of the headphone out. but I will tell you that if you want to build any kind of decent vinyl system, you will need a separate phono preamp if the one that is in the 2170 is any indication.  The one in all three 2170's I've had access to is unacceptable. 

I think the genius of the Lyngdorf is in its ability to take a digital in signal, by USB or coax, and keep the signal in the digital domain until it is output to the speakers.  

Dealer support being what it is (or isn't) you might want to buy a used one and try it.  If it doesn't work for you you can resell it without taking a bath.  

I have a 2170 and am thinking about a 3400.  The increased power would be great to drive my Maggie 3.7i speakers. I currently use a Parasound A21 power amp fed from the analog output of the 2170.  I also use a SWARM DBA sub system.  The 2170 feeds a DAC via the digital output.  The DAC feeds the SWARM amp.  This works very well as the 2170 has only one analog output.  If the A21 was in the same rack as the 2170 and SWARM amp I could feed the SWARM amp with a looping output from A21.  

My suggestion is to purchase the 3400.  You could drive the speakers with the 3400 and drive a quality headphone amp with one of the analog outputs if you don't like the 3400 headphone amp.  If I am correct you can use the BYPASS mode to listen without RoomPerfect while using headphones  Use an outboard phono stage, not the one in the 3400.

I agree customer support is difficult to receive.  I have been contacting Anders Borbye at contact@steinwaylyngdorf.com.  Anders is very helpful but I receive his answers 12 hours or so after I send the email, longer on week-ends.  He is in Denmark.  That is frustrating.  I also live in FL and have contacted dealers but there seems to be no desire to help someone who is not a customer.

I own a TDAI3400 and have a friend with one , you are getting very good advice on this thread so far.

There is excellent UK dealer and owners support on AVforums.com 

It's such a shame that the dealer network in the US is nothing like the UK as home demos were offered here widely and room perfect is truly awesome in what it can do. 

Thanks for your thoughtful responses.

2171 is discontinued? No more software updates?

Dac is old technology? Significant?

2171 can run subs rca out & headphones

Digital coax out to dac and head phone amp combo eg

Chord hugo2 is a very good piece used under us$1800.

Would a 2171 make sense for $3k + $1800

Vsv$7000. for 3400 which I not seen used.

brownsfan  2171 as a purchase today?

Vs pony up for years of enjoyment?

@bob52r I guess my point was that I personally would not put much money into audio if I knew I was going to move from an apartment to a house.  I would wait until I found the house, then build a system around the particular room constraints (if there are any) once I understand what those constraints are. 

As a temporary measure, a really nice headphone system can get you through the apartment phase and perhaps still have value as a second system once you are in a more permanent location.

You mentioned that you have a dedicated, well treated, room in your current home. There is no substitute for assembling a system around your room constraints and then treating the room.   No amount of money is a substitute for that approach.

@bob52r 

the model you are referring to is the TDAI-2170

I would not get an external DAC with a TDAI , you don't need it the AMP is  DAC .

Thanks to the recommendation of another member here, i bought a TDA-1120 and I really love the unit. It sounds really nice and the Room Perfect is amazingly good. Reduced boom in the bass and allowed the music to sound much clearer, I feel like there is just more music coming through and my room is affecting it less.

I may have created confusion

1. I moved from my house with the large treated room.

I sold near the top.

I am temporarily in a rental apartment.  I will.move into a different apartment or townhouse which I will buy when the housing market corrects 

I will not likely have s great treated room

In the future. So room correction is important. 

I want 2 Chanel thru speakers. There will be limitations the volume I can use...without driving my neighbors crazy. 

I must havheadphones.

2170 today? Does in make sense asbit is older and it appears that the software for the 2170 may not be updated nor supported in the future.

Days that are over 5 years old are generally not a wise choice. The lyngdirf systems are generally better than most dac in a corresponding price class.

The 2170 dac? Your current thoughts.

The 3400 is above my budget. But maybe it is worth expending myself???

Brownsfan.       Your thoughts?

The3400 is outside of my buget

Sometimes it is cheaper to buy once for more money than to buy and sell a number of times. I could adapt a 2170 by going digital out to a dac and headphone amp....thinking chord hugo2??

Have a roon external core and endpoint?
