Yes, I could do that, but first I will wait for a response from Monoprice.com to see if they would just replace it. I believe I bought it about a year ago from their website.At this point, I'd probably open it up, take some photos and post them here.
Almost certainly, one of ASR hardware gurus will advise what likely happened, and if it's worth repairing.
There's supposed to be a 3-year replacement warranty.I contacted Monoprice.com to see if there would be a replacement warranty. I bought it directly from their website.
I'm glad you shared that because it reminded me to comment about the change in apparent volume on my unit. I have had mine for about 2 years now and it has always had plenty of power but things like the HE560 used to require high gain and the dial to at least be at noon. Starting a few months ago nothing I own can use high gain anymore. I tried troubleshooting to see if driver or os updates changed the system output levels but regardless of what I hook the LS up to it is louder than it used to be. There doesn't seem to be any degradation in sound quality or an increased noise floor so I am stumped. It's just odd.On a positive note, if you have one of these and are wondering how it drives 18ohm Deva/HE5XX HFM planars, it does great IMO.
I have mine in low gain, driven by an LG V20 'tricked' into 'high impedance' 2V into LS. LS controlling volume. No apparent clipping or distortion up to ear shattering levels. Volume knob still has a ways to go at the 'shattering' point (more than with HE400i) - plenty of headroom even in low gain. Well matched for these HFM IMO.
Do watch your listening volume. Without distortion to make you reach for the volume knob, it is very easy to be listening at potentially damaging levels and be unaware of it.
This is not "warm":

It does follow "the letter" of the definition so IMO it's ok to call it warm/musical. Audible or not is a different discussion and you might be right.Not at that amplitude it isn't.
I know your question is from 2021, but the amp is a fully discrete design by Alex Cavalli.Is Monoprice Liquid Spark a discrete amp ? are there any opamps ?
I'm pretty sure someone did, it's in one of the replies in the thread and it did indeed remove the hum. It's not really an issue though because it's far from audible.i cannot believe that no one has tried a better power supply
The noise must come from it for sure
hi thank you very much for your kind reply This amp is really nice indeed Unfortunately not easy to find in EUI'm pretty sure someone did, it's in one of the replies in the thread and it did indeed remove the hum. It's not really an issue though because it's far from audible.
The gain is actually quite high. You'll notice in the measurements that there isn't much power difference between low (3db) and high (6db) gain. I feel like the amp maybe should have been 0db gain for the low gain to give some more volume pot range with sensitive headphones.hi thank you very much for your kind reply This amp is really nice indeed Unfortunately not easy to find in EU
i understand the gain is low It could be just perfect as line preamp as well
Just for reference, here's how much gain competing Headphone Amps offer:The gain is actually quite high.
Oh, understood.Just for reference, here's how much gain competing Headphone Amps offer:
So compared to that, the Liquid Spark's 6dB is really quite low.
- JDS Atom Amp 2: 13.5dB
- Topping L30 II: 16.5dB
- Schiit Magni Unity: 15.0dB
- iFi ZEN Air CAN: 18.0dB
a +6dB corresponds to a voltage gain of 2 times Quite ideal for a line stageThe gain is actually quite high. You'll notice in the measurements that there isn't much power difference between low (3db) and high (6db) gain. I feel like the amp maybe should have been 0db gain for the low gain to give some more volume pot range with sensitive headphones.
