STI-1000 Overrated or not?


hi to all
i am new to this forum and would like to ask for some advice.
i have a vintage c39 and mc7106 combo which i use for 2 channel only (bridged). i wonder if anyone have heard this combo before for music only? i have just bought a w4s class d int amp (200 hrs running in)wanting to replace them but found it lacking some fullness in the sound especially in bass impact and vocals as compared to the 7106 (using the pre-out from the w4s for ab comparison). Or am i too used to the Mc sound? i know the sti needs more running in time but it should at least outgun my Mc by now. Just confused. Any comments from the experienced guys would be appreciated.

PS my system includes macmini>EE minimax as source and with Harbeth c7.

You could try moving your speakers a couple inches closer to room boundaries. It may be telling you things about your room you weren't aware of before.
Ddd makes a good point.

I had to adjust my speaker location after moving to a Class D Icepower amp in that the soundstage and imaging opened up quite a bit which required re-tweaking of speaker location to get right. Not uncommon whenever a significant change in amplification is made.
I may have bought my last amp, the Wyred4Sound STI-500. I burned it in with a tuner which put well over 300 hours on it. Very holographic and transparent with a very low noise floor which brings out so many little nuances and inner detail that I've never heard on very familiar recordings. Also, the bass.....my god. I NEVER had bass like this before. Deep, tight, accurate and fast. Did I say deep? I had speakers with single a 10" woofer, and two pair of speakers with DUAL 8" woofers and none of them had the bass that my current Source Techs with a SINGLE 7" woofer. Everyone has their own opinion of amps, and there is no perfect amp, but I'm extremely happy with my Wyred integrated. I've owned solid state and tubes over the years.
