I think if you hang around here for a while, you will realize my recommended products as they have general consensus among members and mentioned very often.
So that we make some progress, here are the products I like and often talk about fondly:
1. Topping D10 and DX3 Pro. They are both awfully cute
. The former is cheap, DAC only, the latter DAC+headphone amp. The DX3 Pro is the product I have on my desk and listen to for hours every day.
2. SMSL SU-8. Cheapest, highest performing DAC with balanced outputs that I have tested. Balanced output can free you from a lot of ground loop issues which once you experience, will be hard to remove.
2. JDS Labs Atom, Massdrop THX AAA 789 and Neurochrome HP1 are state-of-the-art headphone amplifiers which no other product can current touch. They are listed in order of cost.
3. JBL 305 Mark II powered speakers. In near field, smaller room setting, they will outperform typical audiophile speakers at almost any price. They are amazingly cheap so even if you don't believe me, you should get a pair and experience.
There are lots more products that are recommended but the above are my current favorites for a variety of reasons.
