Quicksilver V4 amps with KT150

Hi

I recently pick up a 5 year old pair of Quicksilver V4 amps.

I contacted Quicksilver and Mike confirmed that it can use KT150 tubes even though it does not have the latest transformer. He felt the KT150 would be a “significant improvement” over the KT88’s.

While I respect Mike’s opinion I am looking for feedback from anyone using the KT150 in their V4’s before I spend $800.00 or so on new tubes.

Thanks

I am currently using Gold Lion KT-77 tubes in my Quicksilver V-4 amps. Plenty of power for my Proac speakers. Fast and sweet sounding. I have not tried the KT-150 tubes.

Congrats on buying a great sounding pair of amps.

Just curious - what was the recommended bias setting for the KT-150 tubes?

Thanks for the feedback.

The amps sounds so good they way they are but with all the hype around the kt150 and the recommendation from Mike it has me thinking...

Mike said they should be biased at 45ma

Jb, please keep us updated if you go with the KT150s. I would be most interested in hearing your impressions.

I will post my impressions in a few weeks. I just ordered a set.

Just curious what system did you hear the V4's in?

The system consisted of Aesthetix Romulus CD front end, Quicksilver full function pre, Gershman Grande Avande Garde speakers and Omega Micro cabling throughout.
