    Adcom preamp overhaul vs. new A/B splitter + EQ vs. other options?

    Hi all, first time poster here. First, my apologies for the LONG post! I happily discovered this forum fairly recently while on the hunt for an audio community with a science based approach instead of the usual "magical thinking" that unfortunately seems to dominate most of the online audio...

    Is my Rotel RC-1590 preamp THIS bad or am I measuring wrong?

    I have a Rotel RC-1590 preamp and have noticed that when it's not muted there is an audible hiss from my tweeters. This prompted me to hook up my QuantAsylum 402 analyzer and measure the SNR to see what was up. The spec on the Rotel web page lists the 'IHF "A" Weighted' SNR for digital inputs at...

    Preamp with nice volume knob for Hifi & Multichannel Purifi Setup

    Hey all, At the moment I have a Denon X3700 as Preamp, which for the long time fed a Yamaha MX-1 with Dynaudio Evoke 50s, recently joined by the Evoke Center and the Dynaudio Sub 6. Long time lurking and reading led me to upgrade the MX-1 to a Boxem Arthur 4215/E2 which arrived today and is a...

    Audio - Mains noise

    Hi, I have a vinyl player from, I think, the 1980s not sure, as it does not exist anywhere online (Ion iTT02), and I also have this plugged into a Behringer phono preamp (PP400). The output is phono to 3.5 mm jack and plugs straight into my polaroid speaker. Yes, the same company that makes the...

    Is the input impedance of SMSL SP400 actually 47k?

    I'm looking at replacing my Topping A50s with the SP400 as a headphone amp/preamp to my speaker amp. I'm curious to know if the input impedance stated by SMSL is real because my DAC (Denafrips Ares II) has oddly high output impedance which doesn't play well with the A50s' strangely low input...

    Which dac/preamp brands are reliable ?

    As I'm in the process of searching for a good dac and preamp (possibly only a dac used as preamp) I was wondering how reliable the top options really are? I'm a big fan of a well engineered product, both in measurements and in usability and reliability. I guess pretty much everybody is... But...

    Clark "mic booster" CT-1 review

    Purchased at Amazon in hope of obtaining some "free" gain for dynamic microphones. Admittedly, I was lured by the comment made in the name of Ramesh Singaram: Clean gain? Initial voice recording sounded distorted, so I decided to measure the device. All done via loopback on Audient ID4 mk II...

    Preamp recommendation with digital streamer and analog phono

    I’m looking for a streaming pre-amp solution that comes with analog Input (RCA). I will be pairing this with purifi based Boxem Amp, feeding into Monitor Audio Silver 300s Towers. My Music Sources : LPs that I play through Music Hall Classic Turntable (this has a built in phono-preamp) and...

    Consequences of the mismatched impedances

    Looking at various fet-based inline preamps, they all tend to have rather high impedance. For example, popular Klark CT-1 Input impedance 7 kΩ Maximum input level -15 dBu Output Impedance 2 k Maximum gain +25 dB, 10 kΩ load Maximum output level +10 dBu, 10 kΩ load Let's...

    DIY Fet microphone preamp

    There are a few designs posted over the internet (4 FETs in line). Is there a preferred one given the components availability in 2022? Or "just buy the Fethead from Amazon" is the way to go?

    This Preamp could serve my hifiman he400se?

    Hi I would like to ask you a question: I recently bought the hifiman he400se and I want to know if the PreAmp Earman TR-AMP can amplify the he400se to its maximum volume? TR-AMP SPECIFICATIONS: HeadAmp THD+N (2.7V, 32R) <0.005% SNR >114dB Dinamic range >107dB Power: 16 Ω...

    Yulong D11?

    I just saw that Yulong just released an upgrade to the DA10 called the DA11, now with ES9038pro instead of an AK4497, and 5 watts of power at 32 ohms instead of 3. It has a 3.5mm single-ended headphone output and both 4.4 pentaconn and XLR “fully balanced” options. They’re purporting a SNR of...

    Do I Need a Better Preamp or Source Selector?

    I'm a new member of this forum, but I've been reading the posts here for a while. However, I haven't been able to find the right guidance, or perhaps I don't know where to look for what I might need. First, a little background about me. I am an older woman whose husband passed away several...

    Comparing ART phono preamps?

    Hi gang, I went to the hassle of making a table that contains the specifications for ART’s various phono preamps. I currently have a Rega Fono Mini A2D with a dead USB port and am looking to replace it. Seeing as these are all under $100 and the DJPRE II did well here, I'm wondering how these...

    A90 Balanced Passthrough?

    I would like to use my dac with a headphone amp and a speaker amp. To this end, I am thinking of using the A90 XLR-out to connect to my Harman Kardon HK990's balaned input. Here's the hitch: The HK990 XLR input is not designed to be used with a preamp. That is to say, there is no way of...

    Search for Good Mic Preamps

    Hi all, Created this thread to find mic preamps that will be good enough (and hopefully not too pricey) to match the Cosmos ADC's level of performance. How are the preamps below? I'm new to this but they appealed to me after a day of searching and shortlisting. Curious about any other...

    Newbie question. I bought an AVR but I'm not impressed by the sound. If I get a preamp then could I use my AVR solely as a power amp?

    Hey everyone, second post here. I bought a used Denon S540H along with two KEF Q150 speakers, and while the sound is pretty great there is a lot of static noise that is coming through at medium-to-high volumes. I also feel like the sound could be a lot better. Aside from that, I hate the Heos...
