  1. @mitchco Seeing as you have the KEF LS50 and also your comparison of the KEF LS50 with the JBL, I am curious if you have tried the BACCH DSP system from Princeton? https://www.audiostream.com/content/bacch4mac-3d-audio-playback-system It is also very favorably reviewed by Soundstage.com a few times recently. They test out the $25k+ hardware version. There is a $5K MacMini software even slightly more powerful than the $25K-50K versions. They demo with KEF LS50's. https://www.theoretica.us/bacch4mac/ It would be very interesting to hear your take on this new cutting edge tech. I hope to buy the $5K MacMini variant in a few months and use in my second LS50 system.
  2. First of all let me thank you for your book, I like it. Thanks also for this detail set of instructions on the UMIK-1 USB. I think this alleviates my confusion about the synergy with the Acourate software and USB mics. I will finish reading your book to figure out what I need to do. Your statement that I may not need an ADC would be a massive saving for me. Whatever, the case I will learn something from your book and give your firm a call, most likely to fix my mistakes. Best way to learn is to make mistakes.
  3. I did look at this mic ($75), the reason I did not select it was because I was reading to avoid USB mics for the Acurate software. However, for $75 I can try it given such a strong endorsement. I have not bought anything yet and I will contact the software designer before I buy anything. It is actually a little confusing as to what the designer is saying about USB mics, https://www.audiovero.de/en/system-requirements.php# Anyways, your suggestion will save me $2K.
  4. What a pleasant surprise reading this article. For the past year I have been toying with the idea of buying a little too large speaker for my office (already acoustically treated with GIK panels). I embarked on researching (and hearing) various hardware based DSP solutions, Anthem STR preamp, Linn Selekt DSM, Lyngdorf 2170, and Deqx (not heard). However, none of them really moved me like a non-DSP based preamp and amp combo that I heard and had to get. Not sure how I got to this stage but I came across the Acourate DSP Software and the following book Barnett, Mitch. Accurate Sound Reproduction Using DSP. Kindle Edition. I was excited to learn that I could use Roon, my computer, a rendu, and the non-dsp preamp and amp I preferred to tailor the speaker to fit into my smallish room. Now I come to this web site and read that the heavy hitters here are also touting the same path as me. This gives me a lot of confidence on what I am embarking on. I have started to read this excellent book and a novice like me understands it so far. I need to buy some measuring tools next. I will add the following info for the next guy/gal thinking of doing this: My next step is to buy the following items to run the Acourate software. This will cost me $4K new. There are other options to substantially lower the cost, I will spend a little more. 1) Earthworks M30 Omni Measurement Mic 2) Millennia HV35P 1-ch Mic Preamp 3) Lynx HiloUSB 12x16 A/D D/A Converter 4) On-Stage Stands Mic Std Rnd 5) 3' Studio Mic Cable XLRF-XLRM 6) 50' Studio Mic Cable XLRF-XLRM
  5. Would it be possible to connect 2 preamps with 1 Lumin X1. That is use both the XLR and RCA outputs from the X1 to 2 preamps?
  6. I have what is likely a simple question but I want to double check before I buy a 3400. If you use an external amp connected via the analogue XLR outputs of the Lyngdorf 3400 can you get the RoomPerfect corrected analogue signal to be sent to an external amp? I understand that the non-RoomPerfect analogue signal can be sent to an external amp (i tested it). Is it possible to send a RoomPerfect correct analogue signal to an external amp?
  7. Someone earlier on this thread mentioned interest in a comparison of the Benchmark LA4 preamp to the Makua. I was thinking about this tonight and came to the conclusion that I will try the 30 home trial of the LA4 before I spend a lot more on the Makua. It should be interesting to see if it has synergy with the Luxman m900u amp I will get. Got nothing to lose and a lot of savings to gain. I owned the Benchmark AHB2 for a while and I was impressed with the silence of that amp. The LA4 preamp is supposedly even quieter than the AHB2. The design goals of the LA4 and the Makua seem similar, a simple quiet circuit. The LA4 is currently sold out on Benchmarks online store. So there must be a few folks on here that have bought one. https://benchmarkmedia.com/blogs/reviews/la4-review-gary-l-beard-positive-feedback
  8. Yes, expected in around the end of 2019. I was debating whether to take to trouble of getting a demo Makua for my home and compare with the m900u or just get the c900u, your posts pulls me to getting a demo unit. On a side note, the Mola Mola gear seems a lot cheaper in the Netherlands than here in the USA. https://www.audiogon.com/listings/lis9ff8a-mola-mola-maluga-and-makua-combination-solid-state
  9. Actually not asking that since this is a generic question I am posing. I used the Tambaqui DAC as an example since it has a wired Ethernet input and Roon Ready. Another DAC that could we considered with Ehternet and Roon Ready is the new Hegal 590 integrated. I am sure there are others. I was curious if the inputs were of equal quality would getting a Rendu be redundant. BTW - I already have a microRendu but that is not that relevant.
  10. If I got a network switch with optical and used a Sonare OpticalModule to input the optical and output to wired Ethernet to feed directly into a DAC (for example Mola Mola Tambaqui) would this be a better solution than getting any of the Rendu models to convert to USB? Let's hypothetically assume the sound quality and features between Ethernet connection and the USB connection on the DAC are the same.
  11. I am doing that now with the old microRendu. All paths are leading me to upgrade this to the SystemOptique with a Signiture Rendu SE. I have to figure out which DAC to get from likely one of the following: - Denafrips Terminator - Mola Mola Tambaqui (a Sonore Signiture Rendu MAYBE not needed) - Lumin X1 or T2 (in which case a Sonore Signiture Rendu IS not needed) Thanks for the info you guys have posted, it has helped a lot.
  12. Thank you. That was such a clear explanation.
  13. I do use ROON. Would I be getting the full sonic benefit (if any) of MQA by using ROON MQA unfolding as opposed to a MQA capable DAC such as a MyTek? I ask because I am going to buy a new DAC (and system) and figured MQA is something I should consider since I use TIDAL.
  14. Is it possible to do MQA unfolding using the Signature Rendu SE? I am considering a Denafrips Terminator (DT) DAC and it does not do MQA so I was told to look for a streamer that can unfold MQA and then feed it into the DT.
  15. USB to optical (optical network) is something I just learned about. I am going to explore this more. Sonare Signiture Rendu is supposed to now support this.
