Integrated amplifier below 1.5K for Sonus Faber?

I really think that pairing Sonus Faber Concertino with tubes will produce very unimpressive sound. Treble will be non-existing, imaging will suffer greatly,imho.
I used to own Concertinos and Concertinos Home speakers. I have to say that if you like Sonus Faber furniture you must pair it with pretty bright ad fairly powerful transistor amp. Otherwise Sonus Faber's natural lack of good treble and poor, bass-colored sound will be overwhelming.
In terms of realism or imaging no matter what you pair them with they going to sound like a mid range Home-Theater speakers which they are.

@Dkzzzz, thanks for your advice. What is your recommended 'powerful' transistor amp? Will Audio Analogue Puccini Settanta (70W - 8 ohm) consider powerful amplifier for Sonus Faber Concertino Domus?

I may look into Krell KAV 400xi int. amplifier which is around 2.5K to pair with SFCD. If you have the similar setup, please spare me your review and experience. Thanks in advance.

I don't have your speakers so take this for what it is worth,but I'll add a couple of very musical SS integrateds to your mix - Plinius 8200 MK2 (175wpc) , and Portal Panache (100 wpc) (you can contact Joe Abrams at Portal Audio about this I'm not afliated other than as a customer), think they fit your listening taste of warm and neutral - I own both. Now, I also will go along with VM8444 and suggest tubes - I don't have a PrimaLuna, have a Soundquest SQ88 (55wpc ), and have a Consonance Cyber Signature 100 (50wpc) due to arrive tomorrow (check out Agon Guild - Quest for Sound about both)- the SQ88 was pretty nice sounding with the stock Chinese tubes, but switching them out for some moderately priced NOS tubes in the preamp section and SED KT 88s and/or JJ TeslaKT 88s in the power section, and it is sweet. Good luck on your quest. PS I have an Audio Analogue Paganini CD player and if the amps are as good I don't think you'd be disappointed should you choose one

I honestly don know how to make Sonus faber concertino sound good. But I would stay away from anything tube based, as I mentioned before. Tubes might be good for very forward and bright/detailed speakers. But for sonus faber you need good gain , some smaller amps would not control them very well. But i gues you are not looking at small amps.
I heard Rega amps and they were fairly bright sounding which might pair well with SF, but I never actually heard Rega-SF combo.
What i am trying to suggest is ask around for SS amp with real forward sound and at least 100W of efficient power output.SF speakers need their butts kicked before they move.
Stay away from amps that emphasise bass (which is hard to do) because SF by design will color everything with bass.
