  1. Thanks for the link! I was always curious how the R8 would sound when paired with the Heresy 4. This is encouraging. Have been saving up just in case someone is looking to sell their pre-loved Heresy 4.
  2. New Thomas video but no discussion on tubes. Maybe its not coming.
  3. Welcome! I'm sure we take full responsibility for your choice=) I hear you and I got confused too. Not too long ago I came across the Prima Luna website on tube rolling and website said that the gain preamp tubes have more effect than the driver preamp tubes. https://www.primaluna-usa.com/tube-rolling Anyway.. I changed it as part of a set from China Hifi. Maybe I should try rolling the middle tube. Previously I always rolled all. Do try it.. if it works for you. Why not?
  4. Thomas did say he will make a video on the R8 tube rolling. Hopefully he'll bring his friends along. One of them bought a lot of tubes to roll. Was reading through some of the comments and Thomas tested the shuguang from Chinahifi.. I think he said something about clarity and sparkle. I forgot. But having done so myself switching from the stock 6SL7 to the shuguang, i felt it was more sensitive, more natural mid range and really good for vocals. With the KT88 and the shuguang, the bass was a bit boomy and a bit wide and muddy. Switch to EL34, the stage shrank a bit and everything
  5. I'm pretty there already. Just seeing what else Thomas will recommend. I noticed he showed the Shuguang 6SL7 in the video. i wonder if its a sign of things to come. My priority now is a pre-loved Klipsch. Sonus Faber are great but I realise its not that great for music that has urgency. Ya.. he didn't mention or showed your diagrams. I was expecting some reference to you whenever he mentioned a subscriber. Would be nice. But I think we learnt more about the R8 in your journey tearing apart the system than his review. So thanks for your sharing and importantly, startin
  6. Oh yes.. I remember that. There was a video or a photo showing the different tubes one of them had purchased. It is fun.. esp if you want to shape the sound.
  7. Thanks @echorec for sharing the link. A pleasant surprise this morning. Nice review with his signature stories and weird analogies. While a bit disappointing that he didn't discuss tube rolling in this video but great that he's generous enough to make a separate video on it. He even spoke about the preamp bypass which @Atmaj highlighted. I took the plunge 2 weeks ago and purchased some tungsols. for the pretubes. Very big difference switching between the standard 6SL7s, shuguangs and tungsols. The difference can be further tuned with the KT88 and EL34s. T
  8. Thanks @F_Fabio and welcome. Interesting to hear about the issue with the wiring. Can't say I have a problem with the imbalance but I had to experiment coz my speakers are 6 ohms. Folks say to play around the 4 and 8 ohm outputs and see which sounded better. I'm now on the 4 ohm output and I recalled the 8ohm output sounded softer and the soundstage was smaller. Hopefully your advice can help solve the imbalance others are facing.
  9. I recall reading somewhere that the head rest portions of high back chairs will reflect bits of sound, which are more pronounced when you lean back.
  10. I hear what you're saying. And have encountered the same thing. He is usually responsive to emails but there will be periods of silence esp if the diagnosis is already done. He might have already sent out the part. I'm guessing a lot of things are going through him and there's many of us. I sometimes get the feeling he's trying to catch up coz there were some confusion in his email reply to me. Sometimes he will email in the wee hours of the morning and weekends. I think he's doing what he can. Guessing everyone would appreciate the customer offering help but it might then mean an
  11. Hahahaha No need to see a nose specialist but our house pets were so intrigued with the smell that they kept sniffing the amp and the tubes (when they're not on). Think they were getting a bit high. Its great that this thread is now 5 pages!! Well done @Atmaj!! My humming 6SL7 tubes are finally resolved. Originally China HiFi sent replacements but they hummed at both speakers rather than just the right side. I just resigned myself and today a package came from China with another set of 6SL7s!! The missus was like.. what did you buy again?? Hooked them up a
  12. Congrats on your purchase!! I was also impressed with the packaging, esp the foam cut out that fits all the tubes snugly. But man.. that smell was insane. I had to put the box and all its trimmings in the sideyard and the machine had enough juice to perfume the room for the next few days. Having that tube database is a good idea.
  13. I've got a pair of Sonus Faber Concertos and they are about 1.5 ft from the wall. They used to be about 1ft but I also have another speaker that is rear ported, so I pushed the speakers outward into the room. I think one issue is the strange sensation when you have the singer 'appearing' from behind the speakers but then you visually see a wall in front of you or in my case.. curtains. The brain goes .. huh?
  14. Have a smallish room as well. Went for a front ported speakers and I consciously went for warm and non-fatiguing sounding gear. I sit either nearfield so the room doesn't really factor in or about 5 ft from the speakers. I noticed sitting at the other end of the room or more than 6ft away, the music gets a bit icky... Not sure if that's the best way to go but seemed to work for me.
  15. Folks above said it. With COVID19, I can't go into the store. Next best thing is call up and enquire. Politely ask if they can give you a better deal. I won't recommend that you simply click purchase on the website and check out. If the store is willing, they will send you an invoice via email with the discounted price. Then transact from there. Good luck. I got a CXA81 and its awesome.
  16. Yes, I believe you're right. On stock 6SL7, I hear a buzz/hiss when I put my ear near the mid woofer. When I rolled to a shuguang 6SL7, the sound went from a buzz/hiss to a hum. I barely hear the sound when I listen nearfield. Moving back a couple of feet, I can't hear either noises
  17. If you're mainly streaming spotify, I would think the devices that make a difference will be those after the streamer. I'm sure others will disagree but I don't think the streamer means much if its spotify. And I'm not dissing spotify coz I'm a spotify user and I like it. If you like the connect, then get stuff after that. A good integrated will do the job. Of course, it depends on your taste and how demanding you are. I think getting separates allow you to shape your music or compensate if that's how you want to play the game.
  18. I don't have your speakers but in my opinion is yes. They all have different sound quality. I've a bluesound2i and CXA81. Through this forum, met a fellow suburb who has an external dac but wanted hear the bluesound coz wanted to minimise the system and have multiroom streaming. So we swapped one afternoon. So I streamed and ran 1) Bluesound to CXA via RCA. So Bluesound is both streamer and DAC, CXA is power amp 2) Bluesound to CXA via digital coax. So bluesound is streamer and CXA is both DAC and power amp 3) Bluesound to external DAC via digital coax,
  19. Awesome amp. Have used both CXA80 and CXA81. I would say the CXA80 is easier to live with coz of the tone control and buttons! GLWTS!
  20. I think your guess is right. Its been weeks since I sent the faulty 6SL7 back to China Hifi but I have always been running the signal from the pre out from my CXA int amp to pre-in on the R8. And I get the hum from the faulty 6SL7 tube at the associated speaker. Yes, volume control at the R8 does not work. Maybe should ask China Hifi if this is an error in their design. Or having the signal run thru the pre-in and via the pre-amp tubes, they are trying to do a partial Schiit Freya.
  21. I get a bit of buzzing when I switch to pre-in with the stock Wilsenton 6SL7 tubes. When I went to another peramp tube, the buzzing went away but I had a faulty tube that hums. As Atmaj suggested, other input sources are ok. But that hum only came from 1 tube/speaker. The other tube/speaker was quiet. Will be interesting to see if anyone else tube rolling from stock 6SL7 will experience something different. When I get my replacement tubes back, I'll let you know as well.
  22. If you can hear 1m from the speaker, its quite bad. I didn't get any unusual noise from the R8 when I first got it. Sometimes I get some type of feedback noise when I switch the RCAs between the terminals. But after turning the amp off and on (I need to bear in mind the 5 mins delay as advised by Atmaj), the sound goes away. There's a pre-out on the R8? There's a pre-in, which I connect from an external amp's pre-out. But no noise. However, after I upgraded my preamp tubes, there was a humming sound coming out from my right speaker after some time. Its quite faint and
