I think it takes a special person with a EAR for what sounds good and what dosent. A fine truly dialed in system can take a long time to put together through trial and error. Years ago it was more about what store you walked into might have the biggest effect on what sounds you heard, now not so much. Its up to YOU as a dedicated HI-Fi individual to seek out the components that synergize the best. Its not an easy road, if done correctly. IMHO.
