Things are not looking good at the moment...bet the excitement is starting to dwindle...hmm, So, let us fix it.
Return the Harbeth within the return window and replace it with a Yamaha NS5000. Its a great speaker with a similar form factor of a Harbeth. But Instruments will sound like Instruments again with the Yamaha (something you never had befote). Harboth doesn't know about stuff like that. Yamaha is a brand with unmatched engineering aptitude and extreme knowledge of Instruments, since they design/fab all your musical instruments as well. Further, you can't even compare the exquisite fit and finish of rhe Yamaha to the Harbeth garage diy box.
Next, let us tackle the brightness and pain that Wilson might have caused you, .
Well...the following is a good strategy if you are outside return windows...
a) talk up the speaker, sing praise on a few threads and get the merry-go-round riders excited for a Willson purchase.
b) Very quietly, slip your wilson into the classifieds section.
c) Wait for some excited lad to buy it
d) Get the cash and buy a PS Audio FR10, FR20. FR30, etc..i.e. one of those with the ribbon midrange. It has a lot of real detail, etc and is a hifi speaker, but it is also enjoyable. Bright sounding stuff posing as detail is not real detail (one of the cheapest tricks)
You should be in good hands thereafter.
It is very obvious how I have lost the detail which the Sophias gave. The voices and instruments are not as focused...everything is kind of smeared in the soundstage. With the Sophias, on a really good recording the vocals were so realistic and made you feel like the artist was there. I didn’t take note of the albums but there are some which the Harbeth also are super impressive in how musical and realistic they sound.
I feel that I am still early in the adjustment phase of not only setting up the speakers but also my ears and brain getting used to the sound.
I know that with the other Wilson speakers, it was an immediate NO. They were bright/hot in my room and there was no denying this, it was annoying and no amount of positioning had any effect on this sound.
