| Seeking speakers under $3K for 10x12 ft room and driven by 20wpc tube amp I enjoy my pair of Oriaco G6 stand mount two-ways from Tonian Labs. Lively and natural sounding to my ears. I’ve used with both a 20W hybrid and a 10W tube amp with good results. Work great in near field. In your price range too. Owner/Builde... | |
| Rel T/7x sub sound improvement but… I too have a single REL T/7x that I am using with a pair of stand mounted Tonian Oriaco speakers. I found that corner placement worked the best just as REL suggests. The sub is to the left of my left-most speaker. If you have a sub adjusted p... | |
| The Allure of Vintage Audio Gear Tastes change and I think that some older gear have qualities that can be appreciated today. Think of the popularity of single ended directly heated triode amps, horn speakers, and idler drive turntables. Some older units sound remarkably good ... | |
| Speaker wire impedance? Speaker impedance? I'll try to be that "guy in the corner nobody talks to" and shed a little light on the topics raised by the OP. Impedance is somewhat like resistance conceptually, but for AC (as in Alternating Current like the power delivered to our homes or a m... | |
| What are the different Levels of quality in Power supplies Transformers and Chokes The power supply is a critical portion of any audio component and the transformers, chokes (if any), capacitors, and regulator (if any) are the critical parts in a power supply. There are many types of power transformers (PTs) commonly used in a... | |
| Rel sub Yes, I use a single Rel T/7x with mono blocks. My hybrid mono blocks are balanced (+/- referenced to each other and not to ground), so I connect as shown for “Differential (i.e. Fully Balanced)” in the accompanying Rel booklet: Yellow connects to ... | |

| Meter for measuring cable capacitance I use an Excelvan M6013 for measuring capacitance of both guitar and audio cables. It is inexpensive and available from Amazon. The meter is a useful tool. I’ve found guitar cable capacitance to noticeable affect the sound, especially direct in... | |
| Differences in YouTube, Spotify, etc. Amazon HD. I access via HEOS and stream to a wired Marantz network audio player when I want to listen on my main audio system. Decent-rez service with a good selection at a low price because we are already Amazon Prime subscribers. I use mostly ... | |
| Microphonics, Feedback and Bob Carver I recall a series of articles in AudioXpress on a topic similar to what the original poster raised referred to as “Back EMF.” Here’s a link to the articles. After analysis with a lot of math the author determines that Back EMF is not an issue wo... | |
| REL Sub Hum Schematics are not easily available for your Parasound amps so I can’t confirm, but I wonder if the A23 is a fully balanced design and the 2125 v2 is not. This would explain the different results when connecting the amps the same way. Try conne... | |
| Ground Loop? Ground problems are the worst. Sometimes it can take a while to sort them out. The original post states "Different TT but still has the issue whether it's connected or not." So, this means that you get the noise with no turntable connected? Th... | |
| Eversolo DMP A6 with or without preamp eyelai777, your experience makes sense. If a source such as your Eversolo streamer has a variable output with sufficient voltage and current, then you can drive an amplifier directly. This eliminates interconnects, contacts, potentiometers, capa... | |
| Is this describing a blown tube, or two blow tubes? The JJ E34L is a variation of the EL34 which is different tube than the "88" (that I assume is a KT88) that you replaced. Specifically, the pentode EL34 has a suppressor grid 3 on pin 1 which a beam tetrode like KT88 does not have. An amp can be... | |
| Tube Preamp: How many tubes does it take to ................. There are many ways to design pre-amps. And many different designs can sound good based on execution and taste. The basic functions of a line stage pre-amp: - Select from multiple sources - Support maximum source input voltage (no overload) ... |
