Which Preamp "internals" would you choose? Based on picture only

Please don't let country of origin influence, resale, etc. I'll keep it after I upgrade for a second system.  Just take into account the guts inside  (I'm no electrical guru so I am depending on people in the know). Of course, sound quality is the key. I know the Rogue is a favorite..however..it's still $1600. Is the Rogue really just an $800 preamp in a bigger box? I believe I am going to purchase one of these for short term and save up and get a much higher end preamp next year ($3500 +). I do need a pre for the next 9 or 10 months or so because I need inputs (I'm using my Pro-Ject MQA dac as a pre now, no analog inputs---actually sounds better than my Nova pre that I just sold)

All these have features and most importantly...the ability to switch inputs by remote (sorry Mapletree)

The rogue RP-1 is $1700 http://hometheaterhifi.com/wp-content/uploads/2016/10/rogue-rp-1-image3.jpg

The Pro-Ject Prebox RS is $650 http://s23.postimg.org/658xi67bv/image.jpg

Schiit Freya $700 (I would guess Saga is similar) http://www.schiit.com/public/upload/general/freya-PCB-1920.jpg

Also This Pro-ject all analog Prebox looks interesting..no internal pics $360.00 http://www.audioaffair.co.uk/pro-ject-pre-box-ds2-analogue-pre-amplifier?

Thanks for any opinions

Just a thing that comes up when looking at internal shots of gear, is all. If looking at the guts of gear then it’s about how it’s built and with what parts and the solder is part of that.

Solder was never designed (original purpose) to be an electrical connection, it was designed to be an electrically conductive physical anchor for a metal to metal contact situation.

It was shoehorned into being an electrical contact/co-joining material as technology involving electricity evolved. Solder is far from perfect and varies in sound qualities across the solder formula spectrum. In any given piece of gear that possesses circuit boards and soldered components, the solder is, in sonic terms, one of the most influential components in the given box.

Still not sure how this relates to the OPs question.  Are you saying that you can see if a unit uses RHOS solder just by looking at the internal photos?  If so, which preamp uses RHOS solder?

@aberyclark  what happened to "no black boxes"?  Those all look like boxers to me and as I said in your other thread you can really stretch your budget buying used. Or is this a different project?

Since we are going down the Solder hole here has anyone seen any audio equipment using other means of connections, other then clip on connectors usually used at speaker driver terminals? I’ve used wire wrap connections in military grade equipment because it can give a better connection that is more vibration and shock resistant but not sure how it would be for audio signals. Very time consuming compared to a soldered joint but maybe could give a different ( better- worse) sound then solder.


Hay OP not to hijack your thread here with the above, but have you though about a quality switching box like the ones Decware make, many options even can get a volume control on it to make a passive pre. This may work for the short time using your existing DAC.

may other to chose from this is just one example.

yes. This is a temporary preamp until i save enough for a much higher $3000 plus one. I thought i had a nice few months old primaluna dialog snagged here on AG, however, the seller tragically passed away ( see other thread)
