I use a Kemper with built in Power Amp for all purposes after having used many different tube amps for many years (yes, I did A/B comparison with Kemper and Tube Amp)
Soon after buying the Kemper I also wanted to have a little device to carry with me when traveling. The Kemper Stage would be to heavy - unfortunately. That's why I started my loooong quest form my travel amp modeler. Soon I recognized that the tests in youtube would not help much for me, so I started buying all the possible units used, to sell them again, if I would not like them. So I first tried BOSS GT-1, Helix HX Stomp, Atomic AmpliFIER, all of them could not compete with the Kemper for different reasons.
(I did not try the Quad Cortex so far anyway it's a bit too expensive)
I have to say, that I compare the units directly, using Studio Monitors AND a 2x12 Celestion V30 Speaker with a power amp (not tube).
Some days ago I could buy very cheap a used BOSS GT1000 and even very cheaper a Hotone Ampero. Today I did a A/B/C comparison.
(my plan was to sell the GT-1000 and get a GT-1000 core, if it sounded great)
To make it short, the Difference is not that small, all the units sound different. I used the same IRs to be fair and the same Amps.
I often hear, it is a question of taste. Sure, everything is a question of taste. But if something should sound like the "real Amp" ist it really a question of taste if it comes close to that or not? There are a lot of opinions of people writing about these units. But did they compare them side by side? If they did it (and I don't speak about people who sell the units, I speak about completely neutral people) what would they say?
The result for me was at one hand very surprising on the other hand not.
First, the Kemper was the best of the three.... You wouldn't have expected that, would you?
But then, The GT-1000 which is not at all cheap, and some people say that it would sound very good, did not sound real at all. I loaded IRs, experimented with the virtual mic position etc. until I got a decent sound. Then I changed to Kemper - BOOM !! There was the Sound - BIG difference.
Then I did the same with the Ampero. It was easy to get a good sound, user interface and software are beautifully made - respect !! It sounds a little bit digital with some settings (beware of excessive FX use and some digital sounding delays!) but the feel is quite good. I also loaded IRs which is also good with this unit, and then I changed to Kemper. Again, Kemper is better. But not the same big difference as with the GT-1000.
So then I compared same amp same IR between GT-1000 and Ampero. And that's the surprise. The Ampero that can be found used for 140 Euro had the better feel and closer to real amp sound than the GT-1000 which costs used about 500 Euro
What really surprised me was the sound quality of the Ampero with the power amp in the 2x12 speaker... there it sounded even better.
I would not recommend the GT-1000 at all (only if you use it with an amp only using the effects. don't buy it for Amp simulation)
I really recommend the Ampero if you can find it for a good price. I prefer it way over the HX Stomp as well (could not test them A/B but the amp simulation of Helix have some frizzling sound that a real amp does not make, which is a pity, concept would be best) .
Conclusion: while waiting on Kemper Mini (please, please, please CK) I'll use the Ampero.
What do you think:
Did you ever do A/B comparisons?
Are you also disappointed about reviews not saying if something really is not that good?
Did you also experienced that after some times, the ears get used to a certain sound, and if you don't compare A/B/(C) you completely loose the reference?
