Many years ago the acoustics company I worked for was the 4th company to try to put in a sound system in the newly built Crystal Cathedral in So. California. Clearly it was an impossible job and our Lead engineer said they would have to put in sat... 
Upgrade speakers or DAC
You have made a big mistake not having better speakers all along, your system is like having a 500 hp engine and exhaust through a ½ inch pipe.    
Best streamer, don't want Roon, don't want a screen, A DAC is OK but not necessary
@philgo01 This is a tough place for EEs. In a digital circuit the great part is the perfect handshake to the next component it's easy to get a 1 or a 0 right that's the glory of digital in a nutshell. Analogue is a really tough signal to get right... 
Audio Cables: All the Same?
It is very simple to see the difference cables make, simply do a frequency / amplitude and noise test with the old cable and with the new cable the difference is the difference. These aren't magical impressions that aren't measurable, audio is ver... 
You're not a true audiophile unless...
I have more than 1M of sound equipment but I don't want to be called an audiophile  because I've come to find out being and "audiophile" means you have to believe in things that are not true. It's more than a hobby it's like a cult. I'm sad to say.   
Vibration Control
In General solid state circuits are not effected by acoustic vibration. The exception is in cheeper ceramic capacitors they can be effected by hi frequency vibration and the dielectric layers separate.  One of the highest vibration environments w...

@nonoise  I used the very best professional recording equipment at the time including Nagra, Fostex, and Zaxcom, I've spent millions on sound equipment for location recording. Only the Zaxcom recorders were solid state they were the first  company... 
Vibration Control
@nonoise  I do have some experience putting high end recorders and microphones in violently shaking environments in my recording career. When you put a recorder that is solid state with no moving parts you don't have to worry about vibration. In t... 
Active Speakers Don't Sound Better
I started a post about this subject and there were over 69k comments people know active and powered speakers are better in so many ways. powered speakers have amps in them  active speakers can be connected to external crossovers and amps passiv...

@pynkfloydd  I thought exactly the same thing having a little DAC around is a great utility I think I’ll eventually put it into my video editing system until I find my tube DAC. I connected the Harmony DAC to ch 1 (I2S ) and my PSA MK 2 (AES) to... 
LAIV Harmony
@tweak1  I believe they have a preamp on the way. The design is compartmentalized better for internal RF interference like separates in one box. If their preamp is as good as the DAC this company could really be interesting, I could spend a lot le...

@smweber2  Thanks for the kind words. I. moved out my PS Audio direct stream DAC MK 2 and for that matter I moved out all my BHK PS Audio equipment. I really just didn’t like the noise, the PS A BHK equipment sounded wonderful and extra tube like...

I moved out my PS Audio direct stream DAC MK 2 and for that matter I moved out all my BHK PS Audo equipment. I really just didn’t like the noise, the PS A BHK equipment sounded wonderful and extra tube like and buttery but it’s just noisy. The Har...

Just listened to the Harmony DAC and I’m really happy it’s very quiet and sounds surprisingly good. For now it’s replacing my $9k DAC. Amazing.
