SparkoS Labs SS3602, Burson V7, MUSES02, OPA2134PA, High Quality Operational Amplifier Chip for BT20A PRO and V3 (1 Pair 2PCS)

I have heard great accolades on these chips in on line reviews and would like to add my views on my experience.
The Fosi Audio V3 was a game changer in my system after replacing my Quad 606 class A amplifier and Nelson Pass F5 amplifier with them, but after installing 2 Sparkos Ss3602 in the front and adding the Muse 02 in the back my system has never sounded better.
Clarity deeper and wider sound stage is amazing, my system is Yamaha CD-S2100 into a Pontus ll dac into my Magnet PV-02 valve preamp then into the Fosi Audio V3 mono blocks poweting my Trols Graveson OBL 15 open baffle speakers.
It’s the best upgrade in 10 years of searching for the best sound I have heard to quote Molly Meldrum host of Australian show Count down “do your self a favour “ and give these mono blocks and op amp upgrades a go, you wont be disappointed.

Muse 02 in Fosi V3 position 2 and 3 . Position 1 i have OPA ! Excelent

Very nice . I mounted in Fosi V3 mono position 2 and 3 , positiona 1 i have OPA .

Muses02 highly recommended. More natural and more musically pleasing audio.

It's been nearly a month and I have had to buy again from elsewhere.
I asked for a refund, you refused and want to try again.
When, if, your second attempt arrives it will go straight onto eBay.
