| TU-8900 upgrade The end result is different from my expectations! In the 8900 I have replaced the OPTs and the caps. Also the small signal tubes are now Amperex ECC82/12AU7s. WOW. The 8900 with Electro-Harmonix 2A3 EH Gold tubes is just gorgeous and is now in... | |
| Streamer Options Needed If you have a separate DAC the Bluesound Node is fine, I have compared my downloads to streamed files and can find no difference - this is with a very high end, well engineered Esoteric K-01XD SE DAC. I cannot vouch for performance with lesser DA... | |
| How can different CAT5/6 cables affect sound. I think that the consensus is that the sonic differences are caused, not by digital issues, but by RFI or other noise induced in the patch cord leaking through into the analog circuitry. Perhaps I am lucky (or hard of hearing) but yesterday I lis... | |
| How can different CAT5/6 cables affect sound. OOPS. That should have been: I could have been really contentious and asked if anyone has heard sonic differences between T568A and T568B wiring standards. | |

| How can different CAT5/6 cables affect sound. A question for people who do hear a difference between cables. Is your streamer integrated with the DAC or is there a link to an external DAC? The answer to this might provide insights regarding the induced noise theory. Another test for those ... | |
| How can different CAT5/6 cables affect sound. If noise, picked up by non-shielded Cat5 cables is the problem, and from responses it seems that is might well be the issue, would that argue that a Wi-Fi (and thus decoupled) connection would work best? I cannot personally comment on this as I r... | |
| How can different CAT5/6 cables affect sound. OOPS. Thanks Richard brand. Streamers usually use UDP which does not have error correction, so a really bad patch cord could cause data errors. | |
| How can different CAT5/6 cables affect sound. My point is actually stronger than TCP being error free, it is that the submission of the buffered data to the DAC chips is totally isolated from the nature of the patch cords. The data is stored in a RAM buffer and is fed to the DAC circuits by ... | |
| TU-8900 upgrade I did a test of the P3ESRs, I moved them over to my main system and was very surprised at how the sound from approx. $2k speakers compared with that from the $37,.5k Rockports! The lowest base was not there and they were not quite as transparent,... | |
| Suggestions for a holographic preamp? The benchmark LA4 is totally transparent, if the depth is on the recording it is in the LA4's output. This component is relatively inexpensive, about $3k, and can be auditioned at home for 30 days. https://benchmarkmedia.com/collections/a-stock/... | |
| CD's or Vinyl? If the digital source were limited to CDs I'd probably choose vinyl. Between vinyl and high-res downloads I am not so sure. Playing the downloads on my Aurender is so convenient, and the SQ so high it is a strong contender, but the sense of "bei... | |
| Class of operation for Tube Power Amps ALL SET consumer tube amps are class A. MOST PP tube amps are AB, but there are (or were) purist class A PP designs, VAC's Renaissance designs, for example, were PP 300B class A. I did a search for new PP Class A amps and found only kits or inexp... | |
| Your first concert was to see who and when? 1812 Overture & a Tchaikovsky Symphony at the Royal Albert Hall. I do not remember which orchestra was playing. It was 1958 or '59. The cannon's echo may still be running round in the Gods! I was in the local C of E youth club for about 5 ye... | |
| How old is too old? PS. Since others have wandered a bit off-topic, I am 81, I play golf almost every day in Summer and ski for a few hours every other day in Winter. Between seasons I play with building electronics and doing paper engineering for my wife who design... |
