Hey! I have been using Achal’s for quite some time now and it’s keeping me very happy. It’s crisp sounding with clean imaging and the bass is tight and fast. Actually the recording that you may have seen does not really justify the actual sound coz they were recorded on the phone but then in reality they are a compliment to your ears.
From my experience, the drivers need a bit of a burn in (about 80 to 100 hrs) for them to really shine and show it’s true potential. They are not power hungry at all and I know some FM’s who are driving it with a very tiny amp and getting the beat out of them.
They come with 30hrs of burn in while it’s delivered and may be in a weeks time you will have them work to it’s full potential.
@Dharam` and
@shekharmenon can definitely share their experience with Denon 3500 and Vista Spark.
You can talk to Amit from IndiqAudio. He is a great person and can understand ones needs and very passionate about what he does and I think it’s worth your time auditioning it.
