SV128ii is one of the best amps from Sunvallery. There are two versions 15W or 25W with KT170.
It has a crystal clear and powerful sound.

Finally I have the proper speaker to match SV-128ii
SV128ii can drive Stenheim 2.5 to the best of my knowledge...
I will demo this combo in the Florida show...

Hi Victor,The is the best power sound power amp from Sunvalley..
I know there is a drastic difference in power between the Sunvalley SV-S1645D and this amplifier. And I'd suspect there is a difference in sound character between the two. Can you characterize how the SV-128BII sounds compared to the SV-S1645D?
Thank you,

Hi Steve
SV128 is one of the best amp from Sunvalley. Yes SV128 has 15w or 25w output power.
If I want to demo my my 2.5 speaker I will use SV128ii. SV1645 is my daily amp.
I perfer to listen in very low volume. This is why I prefer SV1645.
In exhibition, I must use SV128ii.
You will love both SV128 and SV1645
