REVIEW: SM PRO iNano - Passive Volume Control

you could use either but you will get better long term usage out of a set of adaptors in my experience, meaning you havent got to get a proprietory cable, and you can use standard set of cables and still have a set of standard cables after you are done with the inano (if your setup changes)

resurrecting this thread cus i'm thinking of getting one.

just wanted to know what's the difference between a preamp, and this unit? many of the commercial preamps out there seem to be alot more expensive, and claim less than "completely transparent sound". can those who have the unit advise if you've experienced any loss in sound quality when using the inano?

if you just need a vol control knob to control your a7s, then this would be it.

Another passive vol control knob you can look into is the level pilot. I got these for my bm5a and they're real nice.

All the cheaper passive vol attenuators including the sm patch, nano patch and level pilot have slight channel imbalances at very low levels. Unless you get a goldpoint vol. attenuator or some other obscenely expensive attenuator, you probably won't get 100% balanced channels at low levels.

what is considered low level? <50%?

Resurrecting this thread (if thats allowed) because I'm also interested in getting the SM Pro Audio Nano Patch Plus:

I just had a question, as I looking into passive volume controllers I came across alot of discussion regarding potentiometers vs. stepped attenuators. One example was this:
 
http://beavishifi.com/articles/Volume_Control/
 
From I can tell, potentiometer based volume controllers are cheaper, widely used, and have (slightly) better volume precision. Stepped attenuators appear to be considered more transparent, higher quality, much more expensive, and don't have quite as much volume precision. The most recommended passive controller I've found are those made by Goldpoint (like the SA1):

Unfortunately, they are stupid expensive. A bit more looking around revealed this on Ebay:
 
http://www.ebay.com/itm/Passive-Preamplifier-Stepped-attenuator-passive-preamp-/271011294270?_trksid=p4069.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D2%26po%3DLVI%26ps%3D63%26clkid%3D605552815797276696&_qi=RTM1084480#ht_4352wt_1139
 
It uses a stepped attenuator and its specs seem very close if not identical to the Goldpoints. Has anyone used those before?
