| [#25] Accuphase AAVA volume Dear All; i get reply from Accuphase. Actually i used their Japanese webpage to send an email, i couldn't send email from their English webpage. as i understand from their email (translate by google) it's written in their user manual and not malfunction. Here is the original email..And they attached Chinese and English user manual related page. Left upper part item 2 is mentioning about this.. Thank you all for the support and suggestions.. 拝啓 時下ますますご清祥のこととお慶び申し上げます。 平素は弊社製品をご愛用頂き、誠にありがとうございます。 メールにてお問合せ頂きました件ですが AAVAは電子ボリウムですので、ボリウムを上げ下げしますと 切り替えのスイッチングノイズが出ますが異常ではありません。 取り扱い説明書の注意事項の所に書かれております。 よろしくお願い致します。 *************************************************************************************** 〒225-8508 横浜市青葉区新石川２－１４－１０ アキュフェーズ株式会社 サービス課 清水 裕司 TEL 045-901-2771 FAX 045-901-8995  |

| [#24] Accuphase AAVA volume Hi All Chings.. Well this is actually really not a big problems or issue.. But as LPXFANS said I think we should be perfectionist.. And those are all high price equipments. This small issue is not against of any performance just I wasnt expecting from Accuphase. As I said hope this small problem will not cause any other serious problems, that's my all concern. Let me send an email to Accuphase Japan and hope to get a reply.. If I get I will share with you as well. Thanks for replies.. Enjoy the Music.. |

| [#22] Accuphase AAVA volume 各Ching, the company already know about this problem.......and can't resolve this issue!! [#10] Accuphase AAVA volume Accuphase is well aware of this problem....read quote " Accuphase is fully aware of this but keeps quiet and strives to minimise the issue. This noise becomes quitter and quitter the higher you go the Accuphase ladder. " |

| [#20] Accuphase AAVA volume Thanks caglarborklu, highly believe this is design issue and cannot be fixed becasue this is a variable gain pre-amplifier and using complicated anlog comos switch (using microprocessor control the switch on and off). |

| [#19] Accuphase AAVA volume Hi BatmanamesIA Yes only happens when you move the volume button. If it's stable no noise. Even the gains are max. When you slowly or fast, move it to high or low, the noise come up. Thanks |

| [#18] Accuphase AAVA volume AAVA 線路内含很多cmos analog switch and operational amplifier, 可能是設計問题,未能適應快速扭動volume knob |

| [#17] Accuphase AAVA volume Is it the noise problem happen only when rotating the volume knob? |

| [#16] Accuphase AAVA volume I am suing the preamp gain settings to the minimum and increase the power amp gain. with this setting i cant hear any noise at the moment. i bought my preamp from hifido. Actually ask them about this problem and they keep asking me to change XLR cable, use RCA cable..make this make that.. which i try more than they suggest..But they still didn't accept that there is problem with AAVA volume control. i am quite happy with my preamp actually. My concern is this problem will be worse in future or will cause another problem.. Hope will not. I am a foreigner living in Shenzhen and couldn't communicate with Accuphase dealers here. if anyone get a official answer from them please let me know.. Thank you :) |

| [#15] Accuphase AAVA volume 既然覺得有問題，咁貴嘅機用得條氣唔順，點解唔直接問吓代理，要求合理解釋，修理好為止？！ 係呢度問，就算有人答倒，又唔能夠代表Accuphase官方回答，亦解決唔倒你嘅問題！ |

| [#13] Accuphase AAVA volume Hello There I have the same noise problem with my C2410 and A45 combo. Actually I discovered this problem by chance. I set the gain of the preamp to 24 db and set the gain to max for the power amp. The zzz sound only noticeable when turning the volume button up and down. Even when it's too low or too high the noise is same and only when you turning the volume button. Do you have any solution or response from Accuphase? Thanks |

| [#12] Accuphase AAVA volume 100% analog IC(operational amplifier ) circuit, it means fully analog |

| [#11] Accuphase AAVA volume 請問C38x0 pre amp user. 這麽大左右AAVA volume. 好像沒analogue circuit. 用IC的嗎? 定係無源前级? |

| [#9] Accuphase AAVA volume Thanks your comment. The interesting thing is: The zzz noise only audible when you are tuning the volume knob quickly in silent music backgroud. And only audible when it is playing SACD disc. All cables are Accuphase 7N cables. Speaker is Red Rose R3 (Aluminium Foil tweeter). C3850 is a very good preamp. it is very sensitive and find audible change when change any accessories (like cables, power cord, power filter, etc.). This is a good point but also a bad point. |

| [#8] Accuphase AAVA volume Read this.... 1/2, I know that much has been written about this, and also that Accuphase does not recommend this. However, I did experiment quite a bit in this regard and IMO the digital volume controls in the Accuphase players yields very good results. I am certainly not the only one that has reached this conclusion. IMO there are two main points: First, many say that the AAVA is much quitter than the digital volume control in the player. I say, that all depends about which noise one talks about! The AAVA volume control has an inherent noise which is audible when one uses very sensitive speakers, e.g. my UNO speakers which have a sensitivity of 105 dBs. This has been mentioned also in a professional review (probably by Pacula) where Accuphase electronics have been used with Avantgarde speakers. Accuphase is fully aware of this but keeps quiet and strives to minimise the issue. This noise becomes quitter and quitter the higher you go the Accuphase ladder. I can confirm that C-2410 was noisier than C-2810 which in turn was noisier than C-3800. While overall this inherent noise is not a big deal, viz. when music is playing one can not easily hear it, the important point here is the fact that the digital volume control in the Accuphase players do not exhibit this issue. Second, there is the issue of power amp. Feeding the player directly in the power amp does not always yield good results. With the wrong amp it can sound like a clock-radio, but with the right amp it can sound very very good. I have obtained poor results with A-45, but very good results with A-65. To find out what the result would be one simply needs to try, and to be open minded of course. In my case, inserting the C-3800 between the DP-720 and A-65 yields a fuller sound with better bass and better decay of the instruments. I certainly do not plan to get rid of the C-3800! However, the reality is that feeding the DP-720 directly into the A-65 yields a very good sound that makes if hard to justify the price of a C-2420 pre-amp. My take home message is to be aware of the half-truths told by the marketing departments. Their job is to convince people to buy pre-amps. |
