Title: Torii IV vs. Simaudio 600i
Post by Stefan on 04/09/15 at 04:47:28

Last weekend my friend and I compared my new Torii against his Simaudio 600i. We both have the same speakers (B&W 805N) and record player (mega rp6) which makes it a good comparison. Besides the amp the other main difference was that he has the Moon phono pre-amp with power supply ($3000) and I have a $300 phone pre-amp. Also my room is tiny and his is at least small. We both agreed that the mids sound way better on my system and that the sound stage is deeper and wider. For the higher frequencies we concluded that the cymbals sound more natural on the Torii. For the lower frequencies the Simaudio had the advantage, the drum kicks came faster and with more might. I wonder though if the phono pre amp is limiting the Torii as I hear the same issue via the headphones...
My tube mods compare to original: RCA OA2, Philips 5R4GYS, Cyro'ed Telefunken E88CC.

Thanks Steve for building an 'affordable' amp that makes listing so much fun!

Sounds like a great comparison. The Decware amps sure are something special.

Stefan,  When I upgraded to ZP3 and put a ortofon 2M black cart on my turntable the sound (after some burn in time ) was amazing!!  Project tube box s phono stage and grado gold cart were in use previously. I am a very happy listener these days.

Thanks Acetone, the zp3 is definitely on my short list!

I can with confidence state that it is your phono-pre that is holding you back in the bass dept.  I had a $230 phono-pre and I could never get the bass to exhibit any punch.  It went deep, but was muddyish. Once I got the ZP3 though,  man!   I always thought that either the Torii III or the Monoliths were not up to the task.  Silly me.   It was the cheap pre.   Of course mids and treble improved greatly too.  3 dimensional sound now at my house.  If you have to eat only Ramen noodles for awhile to save up for a ZP3 then do it. :)   You just won't believe your ears once you do.   8-)

You`ve probably got a decent cartridge in Stefan. It`s amazing what bass comes out of them with the ZP3. It`s just so effortless.
