My exp. with Focal Sopra No.2 , Harbeth 40.2, Passlabs XA30.5 and Hypex NC400


Hello. Long time reader here.

I want to share my listening experiences since i bought my Sopra No.2’s last year. I think it may shed some light on people who suffered from brightness on their system. Please excuse my English as it is not my native language.

My other components are Primaluna Dialogue Premium Preamp and Gustard x20pro Dac with Singxer SU-1 via HQ-Player and Roon. Interconnects are DH Labs Silversonic and speaker cable is Kimber 8TC. My room is 45m2 and not treated. I would say my room has some echo and can sound harsh on higher volume levels. (I will deal with this later hopefully.)

I will try to keep it short below:

Sopra No.2’s with NC400’s:
Pros: Extreme clarity with huge sound stage , speed&timing , dynamism , attack , total control on bass , good instrument separation. NC400 allows all this without breaking a sweat.
Cons: Fatiguing after some time , especially with higher volume. Bright and forward on almost half of the music i listen to and neutral on the other half but never warm. (I listen to almost every kind of music though it’s mostly Jazz both with vocals and instrumental only.) Mids and low-mids(esp. on vocals) were not rich and full as i wished.

The fatiguing alone bugged me to change my speakers and my dealer sent me Harbeth 40.2’s to try at home.

Harbeth 40.2’s with NC400’s:
So compared to Sopra No.2’s it was less hi-fi and more of a live music experience with the midrange of Harbeth’s as we know it. Non-fatiguing , just slightly warm ,sweet sound and overall a wonderful match with the speaker and the amp. Believe it or not it was more than just a glimpse of when i listened to 40.2’s with Dan D’Agostino MOMENTUM LIFESTYLE AMPLIFIER. Last weekend we tried the NC400’s with my brothers SLH5’s and i think he is now considering selling his Naim setup which is 6 times more expensive then NC400’s :)

I wanted to keep Harbeth 40.2’s but we could not agree on price with the dealer so i kept my Sopra’s and decided to try a well regarded amp with it. That was Pass Labs XA30.5.

Sopra No.2’s with Pass Labs XA30.5 :
Brightness and fatiguing gone for good. You get the magical warm sound of Pass Labs , suddenly Sopra’s are different speakers now. The amp really has it’s own color as they say. Bass is less controlled and almost too slow compared to NC400’s. I was worried about 30w is not going to be enough for my room but i never miss 200w’s of NC400’s unless i listen to electronic dance music.

I am never selling my NC400’s as they will come handy when i want to listen instrumental tracks or EDM.
For example , Chuck Mangione - Children of Sanchez or Charles Lloyd & The Marvels - La llorona gives you goosebumps when listened through NC400’s while with XA30.5 they won’t impress you as much.
They are really more than their money’s worth but the XA30.5 is still a better match with Sopra No.2’s.

I guess i couldn't keep it short. Oh well..

yoby,

No I haven't yet...

kosst_amojan,

I have read just the opposite that the Focal Sopra 2 are an easy load for an amp. So I wonder what is it?

Will my Carver Raven amp drive the Sopra 2's?

I've paired my Sopra 3s with a Pass XP-22 preamp and a Pass XA25 Class A amplifier. The XA25 is listed at 25 Watts at 8 ohms... but designer Nelson Pass says it easily exceed that, mentioning that it will safely clip at 80 watts. My estimate is that at the volumes I listen to, the Sopra 3s might use 5-6 watts, so 80 watts Class A will never be reached at the Sopra 3s 91.5 db efficiency. The XA25 easily will handle the Sopra 3.

Nelson says the XA25 was built starting with the midrange and moved to the bass and treble, whereas the XA-30 was built from the bass up to the midrange. The midrange on the XA25 is on the warm side of things.

The XA25 will also easily handle the 2.7 ohm dip the Sopra throws at the XA25 at 60 HZ. Also worth mentioning with the XA25 is the HUGE damping factor at 500 . The amp will grab those woofers by the balls and make em beg.
