Je opravdu zajímavé, že tento operační zesilovač potřebuje čas na zahoření, aby ukázal co v něm vězí, je to skutečnost a potom je zvuk opravdu velkolepý, velká zvuková scéna, prostě mohutný a detailní zvuk s pěkným spodkem, který se Vám nemůže nelíbit....jsem maximálně spokojený. Mám Topping D50s..... a zesilovač A50s..... Vložen 1 kus do D50s. Používám jen sluchátkový výstup v A50s. Lidé z Burson audio jsou jednoduše kouzelníci :-)
P.S.: tento OZ navíc oproti standartnímu LME49720, který je v D50s ještě zesílí zvuk, ale také se o něco více zahřeje, ale nezpůsobuje v D50s problémy... co asi dělá V6? Rád bych vyzkoušel....

I'm not a fan of Op-amps, but if you're faced with no other option, the Burson V5i is perfect. The D50s is very compact but fitment was no problem.

You must run a signal through the DAC for a least 100 hours before serious listening... the result is a much better presentation of a sound stage, less high frequency hash and more realistic voice. Every passive and active device will benefit from a breaking in procedure.

saw some people mentioning this was their pick with the Xduoo XD05 line threw one in my basic and wow, made it warmer and fuller sounding.
drawback is that it makes it take longer to turn on and it makes a odd pop noise in sensitive IEM's.
tempted to get another too try in the cheap Douk amp with hot swappable op amps and if I can budget it my next amp will def be a Burson amp

I dropped a pair of thses into my DIY Muffsy phpne pre-amp and WOW! Large improvment over the stock op-amps. I finally have the noise down low enough on my vinyl setup to listem on headphoones. Good product!

Just had the V5i installed inside the DAC and the improvement manly in stage and sensing more details is obvious

This Burson Audio V5i op-amp is sweet! But before I get to that, I want to comment on the service from DIY Audio. In a word - excellent. I initially ordered this item several months ago, and it arrived quite quickly, and well-packaged. After using it in my external DAC for a few weeks, though, there was a problem. Lots of static and pops in the left channel. Uh-oh, defective unit. I contacted DIY by email, and they shipped me a replacement, no charge and no questions asked. Awesome.
So now, I've been using the new one in my system for a few weeks, and I love it. Improvements in sound quality are not drastic, but are nonetheless quite noticeable. The bass is more extended, and very tight. Vocals seem more natural and nuanced. Best of all, the sound-stage is opened up, and individual insruments can be more precisely placed.
Thanks to Burson Audio and to DIY Audio!

The V5i's make together with my Nobsound NS 08E a big step toward performance

I have an Ah! 4000 cd player. This player is a Marantz cd4000 that was factory modified. It as designed to be tweeked. It has a tube output stage. YOu can roll tubes and opamps. There was also the option to add an upsampling chip. I purchased and added the upsampling chip. The improvement in sound was remarkable. However the chip has fried and the manufacturer no longer supports the chip. I chose to upgrade the opamps with the hope of recapturing the sound quality that was lost when I had to remove the upsampling chip.... I would recommend this opamp to anyone who has the OPA604 single opamp and is looking to improve the sound..... It vastly improved the sound of mine without having to use an external dac.
