For speakers: Hindi naman ako particular sa mga brands. But you're in safe hands sa mga reputable brands. Rather than the pang-masa Pioneers, step up into the likes of Morels, DLS, Focal kung kaya.. etc.
MB Quartz used to make competitive speakers, hangang ngayon okay parin sila but over the years.. their sales lagged. Plus, meron sila mga issues dati regarding quality. And so, I'll avoid them unless malaki yun discount nila (parang dati nagka-sale yun Mickey's AutoSounds ng Quartz..)
Morels take 2nd place. I like their tonal quality but their highs might leave you a bit dazed. Madami umaagal that they're too "bright"
DLS is a rising competitor to Focal. Madami na rin nagconvert to DLS especially after hearing their UP6
Focal still remains the industry leader IMO and their brand name alones carry some value

. Probably biased lang cguro ako since I was spoiled with their PolyKevlar lineup...
Verdict: I think you should first "hear" them. Mga ibang tao ayaw sa morel due to their treble range, but I'm pretty fine with it. Magpa-audition ka muna kamo since iba iba taste natin.
So, for me:
Top-Tier: Focal, DLS
2nd Tier: Morel, Cadence
P.S. Wala akong opinions about Fidelity. Targa's quite good too.. bang per buck talaga.. pero kung kaya mo mag-Morel, go for it. Don't compromise on seps..they comprise most of your listening experience.
