A few days ago, I did a comparison for JRC NE5534, Burson V6 Vivid Classic and a Sparko SS3602 installed in a Burson Fun headphone amp, every A/B-test were done with a DIY stereo switch for instantly swapping between the simultaneously powered amps and compairing with my own DIY assembled LBC amp with a V6 Vivid and Sparko discrete voltage regulators SS7815 and SS1117-15, that will replace the original LM317 and LM337. Those discrete voltage regs will really give the amp a steady and clean power voltage with very low noisefloor and a black background.
Before the test, every OpAmp were burned in with pink/white noise and sinus waves for several hours. The test were made with a pair of Sennheiser HD 800 connected with the DIY A/B-switch to both amps simultaneously powered and listening to some CD´s, for example Ani DiFranco and Laura Pausini from 2006 - playing in my Arcam CD192 CD-player. Here are my verdict:
The standard NE5534 was dull sounding with some treble roll off and not as clear and open as all the other OpAmps.
The difference between Burson V6 Vivid and Classic was the smallest between all tested and not as big as many people stated, that the Vivid should be more open with a bigger sound stage and the Classic should be warmer and closer To me, it was almost not hearable.
The Sparkos SS3602 had more treble and sparkle to the sound and maybe the sound was also more open than all the other tested.
When compairing the Burson Fun with my DIY amp with SS7815 and SS1117-15, the later had a noticeable more open sound, and i believe much of that is due to the discretes.
You will not be disappointed with any of this discretes, and also the discrete voltage regulators will improve the sound to a completely different level!
I´m aware there are at least one more discrete in the market; the NewClassD (confusingly working in Class A, and that I intend to review shortly). The SS3601 and SS3602 will cost about 10$ more than V6, and I think this small difference are fair if you like the sound from the SparkoS!
Whatever of the discrete OpAmps you choose, it will give you big step upwards for the sound, and I believe it´s mostly equipment synergy and personal tastes that will make you decide who will be your next buy, and all them gonna make you satisfied!
Finally, I really want to thank Andrew at SparkoS, as he equipped me with the discretes and made this test possible!
