anyone compared the sony ta 707es to the 770es?
707 use mosfet drivers
770 BJT
which is the best between 707 and 770?
''
To the best of my knowledge...The 770ES/870ES/707ES/808ES all use exactly the same circuit boards however they all have subtle differences...
770ES: BJT Drivers/MosFet outputs, "standard" grade capacitors, plastic insulated binding posts & steel top panel.
870ES: BJT Drivers/MosFet outputs, "audiophile" grade capacitors, 25% larger [than 770ES] PSU capacitors, gold plated binding posts, Gibraltar top panel, larger heatsink & slightly higher bias.
707ES: Mosfet Drivers & outputs, "audiophile" grade capacitors, 25% larger [than 770ES] PSU capacitors, plastic insulated binding posts & steel top panel.
808ES: MosFet Drivers & outputs, "audiophile" grade capacitors, 25% larger [than 770ES] PSU capacitors, gold plated binding posts, Gibraltar top panel, larger heatsink & slightly higher bias.
So in answer to your question, yes the 808ES is definitely of better quality than the others... Is it worth the extra ? Not to me but to you it may be
