Thanks a lot for your opinions.
Lyr should be a good amp. Just read the comments on Amazon, and saw some nice reviews about it. It seems you'll also need a DAC (e.g. Modi) to pair with it. But this combo might exceed my budget.
Compared to EF2A, do you think Modi & Magni would be a better option to start with?
Absolutely it would or maybe a Vali instead of the Magni. That is more of a personal decision as some people like tube sound (me for example) and others prefer solid-state, but either combo will definitely get you started in the right direction. I have the Modi dac as well and IMO it is a very under-rated dac.
