Who has Luv for the Lyngdorf 2170 and is thinking about the 3400.

I use Roon with the 2170 perfectly. Love Roon with Tidal. Great combo for sure. I understand the newer features are wonderful.  Hope the more powerful unit is as musical.

Great! Please remember that the unit does not sound it’s best until being on 12 hours. I leave mine fully on, not in standby. The mids and overal tone improve noticeably. This is not a small point and one owners should be aware of.

There are also other ways to get more of that 300 tube magic and I would be happy to help. One involves a mod/upgrade I did to my unit and choice of cabling also Impacts tone and mids.

I, like you, rid myself of all manner of tube gear, cords, and hassle.

@grannyring 
Can you share that mod?
And your cables of choice?

@grannyring Please share what are the ways 2170 can be improved. Mine goes to standby mode when there's no signal playing for some time. How do I prevent that?

@kdude66  Interesting. What USB driver are you using that allows you to stream DSD 512? I'm extremely curious. My system sounds significantly better with DSD upsample, with higher rates the better. Your feedback will be helpful.

I use Pure Audio Project Horn1 speaker. They truly excellent speakers. I use them in my living room of 15'x12'. Its funny how the open baffle horn interact with my living space. Previously my room was heavily treated, corner bass traps, absorber on first and second reflection point, monster bass trap at the back wall and what not. However, since using the PAP open baffle, I had to reduce the sound treatment significantly to make the speaker sound better. It's surprising how it's 2x15" woofer each channel integrate so well in a small room.

What is puzzling is that, after I installed 2170 and took enough measurement to have RP 100%, I do not notice a significant different with or without room perfect. Any idea why that could be? I took 11 measurement (3 additional ones after receiving 100% RP). Also, there's 5' opening into hallway at the back of left channel. I took a measurement of that space too. Is that desirable?

Funny thing is, even though I do not notice a drastica difference between having RP on or off, the sound quality regardless is superb; I mean really really good.

I really don’t want to do so on this thread. The unit sounds amazing without it. I don’t want to derail it. It is only for folks who are willing to nullify the warranty, spend at least $300 - $500, and have advanced skills. It requires taking apart the unit to access the back of the circuit board and then desoldering parts and resoldering new parts that are very big for the space. Advanced skills are a must or the unit will be ruined in quick fashion.

You can go into the 2170 settings and turn off the auto standby mode.
