Review: Violectric HPA V200 amp
May 3, 2024 at 3:23 PM Post #3,061 of 3,079
I have two questions: is the violectric v200 better than the Lake People G111?
Is the v200 a good upgrade to the Asgard 3, does it have more power and quality?
Different sound. Depends on what headphone.

I've had V200 and Asgard 3 in the past but not at the same time, also did not have G111.

So take it with grain of salt, but based from my conversation with another head-fi member and it seems to match what roskodan is saying.

They all have slightly different sound signature.

V200 = warm with rolled off air.
G111 = neutral, more leaning towards studio sound.
Asgard 3 = this one is confusing because people say it's warm but I didn't find it too warm.

Due to the difference in sound signature the recommended DAC pairing are also different.

But resolution wise from my chat with another person he says V200 > G111, and from memory I think V200 > Asgard 3.

So based on this I would say V200 has highest resolution. It's also recommended to buy AudioQuest NRG-Z3 cable to go with it, though I never tried.

That being said, I sold V200 after I got Lyr 3. So this is all from memory LOL.

I have the V200 and had the G111 MKII, unfortunately I don't know the old G111. It would be quite a challenge if the old G111 had the soundstage of the V200. In my opinion all L.P. models they are geared for professional listening and are delicious. The Violectrics are designed for audiophile listening, where musically they have a wider and deeper soundstage and make musical instruments better appreciated (excellent stereophony). If you are looking for a musical amplifier, also consider the Lehmann Linear (sounds divine) and Violectric V100.

more powerful is the v200 or the schiit asgard 3?
Depends on your headphone:

16 ohm:
V200 = 1W
Asgard 3 = 5W

32 ohm:
V200 = 2W
Asgard 3 = 3.5W

50 ohm:
V200 = 2.7W
Asgard 3 = 2.5W

600 ohm:
V200 = 0.57W
Asgard 3 = 0.3W

So at 50 ohm both about the same, at 16 ohm Asgard 3 wins, at 600 ohm V200 wins.

Really depending on your headphone. But they also have different sound signature so it's not just power I think.

What headphone are you using?

I’ve been using the V200 for many years, and lately I’ve been taking a closer look at its hardware, since perhaps it’s time to check its capacitors. At the same time, I noticed that next to the transformer, there is an operational amplifier tl072сp. Since the time this opamp was produced, a couple more generations have come out with improved characteristics, for example tl072ip and tl072hidr. Out of curiosity, I bought both and successively replaced the original tl072cp with new ones, which gave a small but noticeable increase in sound, especially from the tl072hidr.

How old is your V200? Do you always leave it on?

As far as I remember, it was purchased around 2012. I turn it on half an hour before listening, I don’t keep it on all the time.
I'm going to try replacing the 5 small capacitors with something like SilmicII, Nichicon KZ, Cerafine or a combination thereof. But I haven't checked the stock ones yet, maybe they're ok.
Although it doesn’t hurt to check, since the temperature inside the case can be relatively elevated and the years go by. Besides, I'm not sure that stock capacitors are generally the best choice for audio.

How many hours of listening do you do per week or month?

Thank you, you have clarified my ideas a lot, the headphones I use the most are: focal clear mg, hifiman arya v2 and quad era 1.

I can’t answer this question exactly. Sometimes it could remain turned on for days in the early years, and sometimes it would not turn on for weeks. Perhaps an average of one to two hours a day.
The life of capacitors is not limited as one might imagine, its longevity is linked to the maximum temperature reached during use. I have never tried to measure the temperatures of the capacitors inside the V200. When touched externally, the V200 does not heat up very much (maybe 40°C - 45°C). The capacitors can have a life of 5000 hours at 105°C, hours which multiply every 10°C less, approximately 240,000 hours at 50°C. If there are no electronics problems, I can tell you that for 10 years and more you will not have problems with its original capacitors.

While a declared lifespan of modern capacitors can be even 8k-10k, the Jamicon SK installed in this amplifier has endurance of 2000 hours at 85С, as stated by the manufacturer. The temperature inside the case also may be higher than that of the outside shell.
The condition of the capacitors can only be checked by desoldering and measuring, if they have not exploded first. And they don’t have to burn out completely, but can deteriorate their characteristics gradually, worsening the sound.

**** more importantly, note how the voltage delivered (Ua,V) is maximised at 600 ohms. This is important when using a high-impedance headphone.

Comparable data for Asgard 3 may not be available.

Can you attach some photos of your V200 capacitors?:wave:
