DAC/ Streamer - to upgrade or not to upgrade?
Thanks for all the recommendations and suggestions. My only comparison of Roku the way I described is with  Oppo 105, Microsoft surface pro i7 and my iPhone 11pro. The Roku seems to provide better SQ( when using  same Tidal source) . Will certainl... 
DAC/ Streamer - to upgrade or not to upgrade?
Thank you for your feedback. I guess no one has the experience of comparing Streaming using Roku, connecting vua optical to digital converter, and then to my Altis DAC. I have also compared accessing the same  Tidal MQA music via Oppo 105 ( connec... 
DAC/ Streamer - to upgrade or not to upgrade?
Thanks for the correction on Tidal MQA. My Altis Reference is a reasonably good  DAC (retailed $14000 in 1998). The new Black Note retailed about $5000 now and is slightly better than Altis when I was able to compare in my system. I don’t mind str... 
How much difference in Sound quality can be expected from different streamers?
I appreciate the 11 responses from fellow Goners in sharing you experience/opinions. Thanks for jjss49 for referring to your former posts that already touch upon similar discussion point although from a slight different emphasis.  Being new to str... 
Is it worthwhile to upgrade an old but quality DAC?
Thank you and appreciate all for your advice. When playing regular CD using Oppo 105 which connects directly to my Doshi preamp, or connect to Altis Reference which then  connects to Doshi Preamp, the quality of sound seems slightly better with Al... 
Has anybody bought or heard a Chinese knock off amplifier?
Mahgister: Although I am amazed with the in-depth knowledge of some of Audiogoners in engineering, physics and acoustics, reading what you have done for SQ as well as your possession of vast knowledge about history, math and science reminds me of... 
Altis Reference DAC problem and Repair
I also want to express my appreciation to fgeifman for his kind referral of Nick Gowan and Audiogon for facilitating the consultation via  Forum. Nick is a real genuine and kind audiophile technician whom I had contacted once before. Although I do...

Dear gs5556:I really appreciate you advice. Based on your advice I just inspected all the contacts and was able to fix it. Now the DAC is playing without the volume problem. Many thanks. Moses189 
subwoofer to speaker connection
Thanks avanti1960 for your sharing of your experience of achieving good base sound without purchasing a high filter. I wonder if using an inexpensive high filter would achieve similar effect as what you have used, except simpler and easier. In... 
subwoofer to speaker connection
Thanks for the suggestion. I am glad that it is not expensive. I already have tried the Hsu high pass filter which is working out well. I would be interested to compare this MiniDSP. I wonder if anyone has experience comparing these 2? Moses189 
subwoofer to speaker connection
Thanks. What is the cost? The basic connection is similar to Hsu high pass filter.  I wonder if anyone has compared both and give an evaluation.Moses 189 
subwoofer to speaker connection
I am glad to hear the improvement with the connection of my subwoofer +high pass filter. I am happy with the improvement and not in a hurry to further upgrade, assuming the next upgrade will be expensive. Will look forward to hear your experience ... 
subwoofer to speaker connection
 I have tried the sound with and without  the Hsu bass optimizer.  I found that  combining my subwoofer with Hsu bass Optimizer with cross over at 60 Hz  to my amp,produced the music a fuller range.  The base part is especially better when listeni... 
subwoofer to speaker connection
Thanks for your comments, gdnrbob.  I wonder if anyone would like to further comment on future upgrades of my system since spending $1500 for  another Lectron JH50 amp will not provide any tangible gain in the sound (to be used as monoblocks) afte... 
subwoofer to speaker connection
Thanks both  bdp24 and stringreen for providing the "scientific" reason in having bi-amp. I will for sure buy the Hsu high pass filter and will be looking forward to detect the difference. On a sonewhat separate but related question I wonder if yo...
