ATC scm 19 upgrade ??

Avocet can be similar than benmarch but avocet is far superior used in hundred of mastering rooms

I did not mean to imply Avocet is comparable in quality to DAC1 - I just read Bob Katz review thats all. I don't know this Avocet at all - so I simply googled it and found that Bob Katz says, "So, what does the Avocet sound like? For digital (PCM) sources, its DAC sounds indistinguishable from the Benchmark, one of the best DACs I’ve heard regardless of price"

I usually work at 65/70db but I feel important change from 70 to 68/65(1 steep down in avocet)

=> In this case something is wrong for sure. I don't think it is a speaker choice problem - something is broken or not operating correctly. If the image moves slightly then you can suspect one channel or the other in the chain - it could be speaker, source or amp or coupling between source and amp. FWIW: If you are controlling the volume with the Avocet then extremes in attenuation are best avoided as that is where any volume control is usually at its worst. If there a way you can attenuate the Bel Canto (does it have trim pots?) so that you drive the Avocet higher in line level signal into the Bel Canto then that would be the next step that I would try. Volume attenuation does strange things even with high end gear when at extremes - it can affect noise floor, dynamics, imaging and frequency response in subtle ways.

get headphones, and keep the atc's.

I have HD650 and really I don´t want sell them

I doubth about speaker cable.

How do you connect your atc´s ? bi-wiring?
or single cable with his standard gold jumpers?
I use atlas hyper 3 single cable and jumping with yba cable

thanks guys

How do you connect your atc´s ? bi-wiring?

My passive 20's are the old kind with no biwire posts ('95 model). I run monster cable from the power amp to the binding post - no spades on either end but everything good and tight.

The reason I warn you about extreme volume attenuation is because if you listen close near field (0.5 meters sitting at a computer workstation) then you will get about 91 db SPL at for 1 watt from the speakers. If you listen at 65 db SPL then you are talking 2.5 milli-Watts to the speakers. If you source music is really good or excellent from a raw recording and uncompressed (say 60 db of dynamic range) then the lowest audible signal (in theory) is 2.5 nano-watts.

These signals are starting to get very small - you may be bumping into non-linearities of electronics and or speakers at these levels.

There should be attenuator trim pads or something like that go between your Avocet and Bel Canto S300. That way you can run things with the volume contro at 2 O'clock instead of 8 or 9 O'clock.

Sorry if this is all ho-hum to you as you know all this already.

Hi shadome
very helping post
I´ll search any xlr attenuator for that.
After all this I think my jumper are very crappy thing.
I put the standar gold of atc and big ddiffference..
Someone advice me about zu ibis jumpers.
