To OP.
Sorry for this, I mean no disrespect, but I'm going to be blunt..
Tautech is right.. This is getting nowhere. I will try to summarize what others and myself think..
You seem to have very strong opinions about things based on little knowledge, and some misconception.
1. USB scopes are plenty fast, it's just they have no buttons. Picoscope 3000D can get up to 100000 WFM's per second. It is more scope than most of people need, with some very advanced features. But some people need (want?) physical scope (with buttons and no PC).
2. You say you want tools to work on audio. Good. So you need a scope that doesn't have much bandwidth, and has low noise and high sensitivity, so you can see signals from microphones and MC pickups and such...
3. I'm still confused about need for X-Y display (apart from oscilloscope art). Do you use it as an audio vectorscope? Could you please explain it a bit more, I would like to know more about it.
- Rigol DS2102A (2GSa/sec, 100MHZ 2ch, 500uV/div)
- Siglent SDS1104X-E (1GSa/sec, 100MHZ 4ch, 500uV/div)
- Siglent SDS2202X-E (2GSa/sec, 200MHZ 2ch, 500uV/div)
- Micsig TO1074 Plus (1GSa/sec, 70MHZ 4ch, 500uV/div)
All of these are up to some 600 USD. If you really need 4ch, then I would chose Siglent SDS1104X-E (1GSa/sec, 100MHZ 4ch, 500uV/div) for audio equipment.
It is waay more capable instrument than DSOX1204G despite not being fancy name.
It is more scope than you need for what you described.
And you get all the digital decodes and very long memory that will be useful at frequencies you're looking at.. And it is fast and OK to use.
DSOX3014T is not a good scope for audio. It is meant for other uses...
For the rest of the money up to DSOX3014T, keep the analog scope you have for X-Y (i agree with Dave), and find a good used Audio Precision audio analyser. Or buy QuantAsylum QA401 Audio Analyzer... Or keep your ARTA setup, it is probably more than enough.
You seem to have decided to treat yourself with "premium product", you know you don't need it, and now you want us to persuade you it's worth it.
In your case it's not.
Nicer knobs, nice logo on the front and actually worse specs for your use case are not worth the money.
Just buy Siglent SDS1104X-E and be amazed how good it is compared to what you had before.
And if you have leftover money buy other specialized audio equipment, because if you want audio measurements, there is no scope in the world that comes even close to even the cheapest audio analysers. You don't like the knobs? You'll get used to it after a week.. EVERY new piece of equipment feels weird to me when I first start using it. MSOX3104T felt weird too at first, and I had to remember where the options are (there is ton of them), had to remember it has touch screen etc etc... After a week or two, it became normal.
This is what I would do in your position. And it seems all the responders mostly. You don't need a poll. People already voted.
If you want to buy "premium" product for the purpose that it will make you feel better that you have treated yourself to something nice, then by all means do it, it's your money.
Hope you don't take this the wrong way.
Best regards,
