I think I know a bit of what Andre is alluding to. I play my music fairly loud but it is easy to talk whilst the music is playing. Any louder than that is often the result of trying to make up for poor dynamics so it'll be a poor system. I also have a thing about natural rather than forced (faux/over-bright) detail.

Real solder is better for sure though I've used lead-free and had no problems providing I turn up the temp on the iron. The joints look matt, which isn't nice. I see little point for diyers using lead free. Mass produced goods... that's a different matter.

I've had similar here and on a couple of other forums. On Android I can close the new window the popup opens but it is a pain.

I'll try to comment tomorrow. I have some thoughts though I've no idea about the distortion.

This is quite some bake off. Looks like tremendous fun.

The production of batteries for Teslas isn't so green and what happens when the batteries need replacing? I've heard some say the car is just about a write off at that point, I've no idea whether there's much in the write off thing but I'm sure the batteries won't be cheap. I've been in one of the Amsterdam Tesla taxis, they certainly are very rapid and quiet. A friend of mine has a deposit down towards a Tesla and he told me that free (sic) battery replacement when required was all part of the package. I don't know, just passing on what he told me. A quick check for the 85 shows they have an 8 year unlimited mileage warranty. Outside of this the replacement cost is $45,000. On a 60 it's a 125,000 mile warranty. I don't know the details for sure, I expect though they have the new compact model setup in a way that works for the mass market. I've not gone into this in any detail, for sure it must be in the business model and TCA for the customer.

It's one thing for Toyota to subdidise the Prius hybrids with battery replacements. Tesla I don't believe can do this as they don't have the financial muscle of Toytota. The problem for them is much greater too as we're talking pure electric cars. BTW to properly charge a Tesla you really want to use 3 phase....

Could this be the reason Nico was in the "wrong" engine mode before their famous coming together?

It shouldn't do, Clive, as the Wi-Fi dongle sits proud of the case. I must say the metal case is excellent (if an exercise in 3D puzzles to assemble) and looks the part. Even on a 3 where it's integrated on the pcb?

Thanks Chris, that's good to know.

I'm interested in the hifiberry metal case. I'm concerned that it would degrade the strength of the wifi connection. Or is metal not an issue at wifi frequencies?

It looks very interesting and innovative. At 4,100 quid maybe they offer a free repair service....

That setup should be absolutely fine. If it sounds good to you then don't fret over some internet comments. Adding another volume control with an extra set of interconnects adds complexity aside from cost. I'd be surprised if you have a problem there, the Caiman is ideal for what you are doing. Enjoy what you have and keep it simple.

Artist 5s are better at 30k input impedance. I'd have thought a Caiman would be fine if the interconnects are short but that's a problem with active speakers unless you keep the speakers close together..
If the sound is fine then simply enjoy it. There's no need to spenf money on a different passive pre.

Were the active speakers Adam A5s I wonder? 10k input impedance.....crazy! Very passive unfriendly. Of course active speakers may have long interconnects too. It's all a recipe for disaster (in terms of SQ).

My Digi+ has arrived and is performing really well with the RPi 3. The SQ into my Octave DAC is on a par with the BugHead player in it's quick startup mode. To get the most out of BugHead you have to run it with the screen off and with some other settings which result in extended startup times. BH in this extended mode is still a just little ahead of the RPi but I wonder whether an iFi spdif reclocker might make up the difference. I also wonder now what to do for my 2nd system, maybe I'll try a Digi DAC Pro.

I'd expect active speakers to be a line level load. The pre-amp (whether it be a passive pot, a variable ouput DAC or an active pre) should just be 'seeing' the inputs to a power amp. Surely this is entirely a matter of the quality of the pot in question, no more, no less? If you have a really easy load of say 100k for a typical valve amp then a 10k pot will do fine. Use the same pot into a 20k load which many solid state amps are then the source can slew into such a load. Modern opamps shouldn't behave too badly but it's not just about the quality of the pot. You'd expect the pot value to be around 1/10th the impedance of the power amp input. Frankly an even ALPS Blue should do pretty well in terms of quality. If there's a real problem here I suspect an impedance mismatch. Bear in mind that the source has to drive the passive pre and poweramps, whereas with an active preamp the source only "sees" the preamp. Maybe the i/cs were high capacitance and therefore attenuating the treble. Again its dependant on the value of the pot. It's not bad design when this happens, it's bad system matching.

You need to understand the specs. If the active speakers are a tough load then any passive pre might struggle. You might be better with an active preamp. The comments on the other forum suggest to me it's the speakers which are the issue.

Clive, note that manhattan24 is quoting something he read on another forum, hence my blunt response! For sure it's meaningless without context and not at all in line with the experience of many others. Probably it's like saying a Ferrari useless - you then find out it was tested in an off road situation. Yes I agree, it's BS.
