OP has speakers already. They are 90db 1W/1m in his original post manufacturer is Piega. Might be the Coax line. If so nice speakers. Worth driving well.
I would be searching something near the 250W/ch @ 8ohm or more, 0.1 Farad of capacitance min and 1KVA torridal transformer min. Not saying a nice Luxman won’t fit the bill however moving up the power scale will help tremendously.
My decision (I’m a metalhead too) was to purchase something that can do almost anything very well and leave that component alone for a very, very long time. For me I purchased a Pass Labs X350.5 as a power amp moving away from the Luxman M02’s I purchased in 1987. Once the power is done for me I can focus on preamplification and sources. I have a good smattering of speakers so I am good there for a while too. Used the same process of getting what I need for what I listen to......
Cerwin Vega AT15’s for some dancing fun when company comes over or if I just want to wail on it with say.... METAL!! Stratovarius Visions of Europe. Excellent power metal.
Monitor Bronze used for connecting anything new to the system just to ensure that if something goes wrong (short in a cable) then good chance this will be the failing component, at a low cost.
PSB Stratus Gold I’s because they were a great deal for a rather quality speaker that can lend itself to projects like fully active.
Day to day
For the delicate stuff Maggie 1.7’s with active crossover and subs.
For the main’s Krell Resolution 1’s.
Exchanging gear can get costly so I prefer to make moves that I won't have to make again for a while such as in amps, preamps, turntables, etc. Rule is if I buy something I have to sell something. For speakers it's a bit more fluid but if OP has the Coax line then I would stop there!
