I heard them with Simaudio Neo 340i driving Vandersteen VLR-CT speakers.
Also, with Hegel H120 driving Aerial Acoustics 5T and Dynaudio Confidence 20’s. Pairig with speakers is more relevant than the integrated amp IMHO. I’d say the above combo’s worked great.
Integration in the room and with the speakers are critical, with the integrated secondary. If an integrated does not pair up with the sub I’d question the merits of the integrated.
