Next step is a good usb cable and make an furutech rca cable with raw cables!

OP... CEI was a distributor that sold quality tubes made by other manufacturers. Zaerix relabeled other manufacturers' tubes. I found a couple in used components. https://www.18watt.com/viewtopic.php?t=23510 Buying tubes for $20 without etched factory codes or test results is a shot in the dark. Even if it sounds good, it may not last long. And with rebadged tubes and no description, you won't know their sonic signature. My advice, spend some money and buy from a reputable dealer who posts tube measurements and offers exchanges. There are many good NOS tubes for $50. |

*zaerix cv492(not zaeux) What is this?! https://drive.google.com/file/d/1SxRg18P1ipUnBRWOjlHb0pC-gC1aVMfG/view?usp=drivesdk |
What about this one?! https://drive.google.com/file/d/1Y_ZxGf1tJqSGpikc3ym3JhLfUob389u-/view?usp=drivesdk |
Hi..i found this tube for 20$ I want to know is it original? https://drive.google.com/file/d/1GDYl5h2hOR3SwxyiBlEIMcDKVqerONH_/view?usp=drivesdk https://drive.google.com/file/d/1-zm3EtQpsraJdpqIOm5Wic2_-gVlC4nB/view?usp=drivesdk |
Adding a power strip is an upgrade over your previous setup. Your system may not be revealing enough to notice a change in SQ, but your components are now getting better current delivery. RCA makes great tubes, all provide a lush, liquid midrange and clear highs. But you may be in need of a more neutral tube. |
Its my equalizer for reducing so much bass and it isnt normal at all https://drive.google.com/file/d/1y6GdU4PQIvw4X51ptRaOAYPNde6tNERM/view?usp=drivesdk |
I bought power strip and no change in my sound I should say again that my sound quality is perfect except bass that hasnt detail I think other option is buy vacuum tubes What do you think about this one? https://drive.google.com/file/d/1RS1lS9KAkuczwXNhwXoKiNAHdKIs-75a/view?usp=drivesdk |
@lowrider57 Its my speaker test with slow music https://youtu.be/ESO7NiVMP1M think its very good and im quite happy But it cant handle fast and sophisticated genre like trance and metal and even most of pop musics |
Wiremold is a well-built power strip that is transparent, meaning it doesn’t colour the sound and no filters are used. This is not a power conditioner, but is much higher quality than using a multi-plug for your components. I use a Wiremold with surge protection, meaning it has a circuit breaker to protect against voltage spikes. https://www.mscdirect.com/industrialtools/wiremold-power-strip.html Use a strip with the shortest 3-prong cable. Typically an amp is plugged into the wall receptacle and source components are plugged into a power conditioner to help filter noise from the power line. As mentioned, Brick Wall offers surge protection and power conditioning; the result is a noticeably lower noise floor. Furman is another good power strip/ conditioner. Brick Walls are available used on Ebay. |
@lowrider57 can you suggest me a good power strip? I see they say connect your amp directly to the wall socket ac,how can it possible when i should use a power strip? Sorry for my noob questions And another question If i can change my speakers with a good audio physic or dynaudio speaker or buy good power strip+power cable+new tubes+usb cable Which one is better choose? I just can select 1 option! |
+1 to Loweider57, he is spot on with all advise . At your price point Tungsram and EI are your best bet . Telefunken is the best overall . Once you go Telefunken, you’ll never go back . I have a pre that takes 2 12AU7’s . I have about $ 2500. invested in 12AU7’s alone . From RCA to G73-R Telefunkens. The smooth plate regular grade Telefunkens are the best bang for the buck . When looking, Tungsrams might be relabeled as RCA or Raytheon. If you want Telefunken sound but a little brighter , try the Nickel plates . Happy Hunting , Mike. |
Bloated bass could be caused by speakers positioned too close the the wall or by the amp not having enough power to drive the speakers. But, your amp shouldn’t have this problem. It could also be caused by the choice of tubes. And lack of dynamics is often due to tubes. Your power setup could be causing lack of dynamics and muddy bass, but I wouldn’t call it bass bloat. It would be a lack of clarity or transparency. Your components should not be plugged into a cheap multi-plug, especially the amp. Amps need unrestricted clean AC feeding them from the wall receptacle. As stated before, I recommend that you use a power strip with a short cable (under 6 ft). Also, replacing the stock cable on the amp would provide better sonics; better dynamics, transparency. I think you should start by improving your power to all your components especially the amp. |
The New Sensor Svetlana 12ax7 is a very good sounding tube. I have yet to try a Gold Lion 12ax7 in my amp's input but I have tried a bunch including some nos and the Svetlana is one of the better sounding current production. JJ ecc83 were dark in my amp, Sovtek LPS were ok but not great, mullard repop good, tungsol repop good but a little too much energy on top. The Svetlana is currently in the input of my amp |
Mehdikh423-Following up on Lowrider57's suggestion. I purchased Brick Wall audio surge protector and this helped lower floor noise on my Cayin 50T amp. https://www.brickwall.com/products/eight-outlet-audio-surge-protector |
It's good that you only hear noise when up close to the speakers. The fact that the noise is constant even with volume down either means your amp is the problem, or more likely it's due to noise on your power line. This is the noise floor of your system, the goal is to lower it until you have a "black background." Your AC line comes from the power grid in your city/town and is shared by everyone in your neighborhood, then it's wired into your service panel, then travels thru all the circuits in your home. At this point your electricity is contaminated, or polluted may be another way to describe it. A power conditioner is typically recommended and/or a dedicated line to lower the noise floor by isolating your system from the rest of your devices and appliances. Your budget will determine what kind of power conditioner to use. A basic unit would be a Furman power strip/conditioner. |
Can you hear noise (with no music) from your listening position or only up close to the speaker? It could easily be noise from tubes, but your power setup is far from optimal. You should use a quality power strip or a strip with power conditioning, not a multi-plug. It's like you're choking the flow of electricity (AC) going to your system. In addition to the Vincent, what are your components? |
Agree with @roberjerman on all points. Your noise floor may be too high and your choice of music is not reference quality. Also agree to try using a well recorded symphony to help tweak your system. A revealing setup will present layers of instruments with detail and separation between. It may not be the fault of your amp, but you need to use low-noise tested tubes. Face the fact that it will cost you more than $40 each. Out of your list the Raytheon may be the most revealing, but testing for noise and microphonics is a must. Telefunken or Siemens are really the way to go for transparency and low noise. Andy at Vintage Tube Services sells very low noise tubes, but only takes phone calls for orders. You tell him what you're looking for and your budget. The noise floor is also affected by dirty power in your AC line. With the volume up and no music playing can you hear any noise or low-level hum thru your speakers? |

For new production tubes, this is a good reference. In my preamp, the EH gold pins sounded much better overall than Mullards. https://www.tubedepot.com/tube-comparison-tool |
Good comments here and I have reviewed this extensively for my Phono Stage. Check out Jim McShane at mcshanedesign.net for Tube needs. I bought these from Jim and they are New with a number of good comments in the chat threads; *Sovtek 12AX7LPS tubes, very low noise spiral filaments, checked for good section-to-section match, $14.75 ea., or $29.75 per matched pair; quads (if available - these are VERY rarely needed) are $61.50. For specially selected tubes (for Aesthetix and other hi gain/noise sensitive gear) selected pairs (when available) are $37.50. These are great for sockets where a good quiet tube is needed, and the tone is top shelf. My tube of choice for Citation phono stages! |
