Supratek Owners Thread

Well, I finally received my Signature Grange preamp after about 6 month long wait.

I initially had ordered the Cortese LCR but later upgraded my order to Signature Grange.

Mick has been wonderful to deal with.

Currently the Supratek preamp is mated with Pass Labs XA30.8 and running stock tubes provided by Mick.

The preamp has exceeded my expectations. It is one hell of a preamp. My previous preamp was EAR Yoshino 868PL, which is a great preamp as well.

Comparing both the preamps, the Grange has more body and dynamics, tonally more rich and overall more musical. Bass is more well defined as well.

The Grange looks like a fine instrument. It is the ONLY audio component that my wife complimented on...which says a lot. LOL

Thanks to everyone on this thread for providing feedback on Supratek and Mick.

I changed my stock rectifier tubes to JJ rectifier tubes in my Supra pre. The new rectifier tubes have about 30 hours on them. Bass seems to be lower than I am used to with the stock rectifier tubes Mick provided. 

Do rectifier tubes also need burn in? 

I tried Ingress rollerblocks under my Grange and heard some nice sonic improvements. 

From what I understand they are similar to Symposium rollerblocks but at a fraction of the price. I might try them also under the Supra power supply unit.

There are few forums mentioning the Ingress products as well.

Great thread!

I am pondering Supratek Cortese LCR preamp. Currently have EAR Yoshino 868PL which is also a full function preamp and is currently paired with Pass Labs XA30.8 amp.

Just wondering if anyone compared EAR preamps with Supratek? The EAR preamp is very good, absolutely nothing wrong with its pairing with Pass Labs but I am looking to get MORE air, bloom and realism in the music.

@reimarc Thanks!!!

Thanks everybody on this thread for sharing your experience with Supratek/Mick. It was extremely useful to me making my decision.

I just placed an order for Cortese LCR preamp/phono.

I cant wait to receive and hear this preamp. It was go against my current pre - EAR Yoshino 868PL preamp so stakes are somewhat high already.

I will share my feedback..in few months once I receive it..

Cheers.

Little update on my Cortese LCR order that I had placed with Mick a while back.

I decided to upgrade my order to the Signature Grange.

Can’t wait to receive it from Mick.

Hope I have done the right thing and hope the 16 tubes won't heat up my room!

LOL.

Anyone have Supratek amplifier? I'm so happy with my Supra preamp that I am thinking of a Supratek 300B or EL34 amp. Any feedback would be appreciated 

@jslateiv thanks! I have been in communication with Mick but I can't decide if I want a 300b or EL34 Supratek amp to go with my Grange..!!!!

@tksteingraber @noromance thanks very much!
