I bought the DIP Classic to use between my Sonos Connect and Amplifier with built in DAC; it has exceeded my expectations, adding a wider and more natural soundstage, giving the sound a much more organic and analogue feel. I can thoroughly recommend it for cleaning up what can be a muddled sound when using the Sonos as a source component.
Subject: "Problem" solved...
Hello Mr. Poon,
A few days back I sent you an e-mail praising a SM70 PRO I purchased from eBay. I also added the unit buzzed a bit.
Yesterday I fed it from a Balanced Mains Unit. This stopped the buzz completely.
The UK mains voltage in my house is a high 246/247 volts. The Manufacturer of the BMU wound the transformer in such a way that the voltage on its output was a more benign 230 volts. Whether the drop in voltage helped, or the blocking of DC helped, or just the operation of balanced mode helped, I know not. The end result is silence. And what a great bit of kit your amp is.
Now, pre-amps: do passives work, or do you not like them? (I'm thinking minimalism!)
Very best wishes.
Due to the large amount of positive feebacks for DIP, I thought I was ready for this.I was wrong. The change in soundstage depth is simply awsome, voices seem to come out from nowhere.And the increased air, lots of air, among instruments really makes the musical message shine in each and every subtle nuance.I don't know how much break-in time is mandatory for DIP's best performance, anyway, as far as I'm concerned, I feel myself in heaven just after a few hours of use.
My cd player is Musical Fidelity A1 CD Pro used as transport paired with Audio Research DAC 2. Not quite a budget player and a well renowned converter. Well, DIP has raised the bar though. And it did it significantly and magnificently. For shure one of the best buy in all my audiophile life.
Congratulations Mr. Poon!
