Naim preamps ensure that no nasty ultrasonics get through. Exactly. I use 82/SC/250. Sounds pretty good with SB3/Bolder mods. -- sonofcolin sonofcolin's Profile: http://forums.slimdevices.com/member.php?userid=9291 View this thread: http://forums.slimdevices.com/showthread.php?t=31865 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

The reason why you need to use a Naim preamp with their power amps is because Naim power amps rely on being fed a bandwidth limited signal. Lots of high frequency (ultrasonic) energy can drive them into instability. Naim preamps ensure that no nasty ultrasonics get through. I'd have thought that, assuming the Transporter has proper anti-imaging filters after the DAC, it won't be putting out any ultrasonics anyway, so you're probably safe. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=31865 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

There's just 2 boxes in my system, running into Shahinian Arcs: Transporter - NAP250. Nothing else, no preamp, no Hicap or any other power supply. Very minimalist and sounds great. Although I do wonder whether not using a good Naim preamp (82, 52 or higher) is reducing the sound quality of the power amp. I have read many times and it's also stated in their own manuals that Naim power amps shouldn't be used without their preamps, but if you've only got one source and that source also has attenuation control and a volume control, then why not. I would love to hear from anyone who has 82, 52 or higher preamp and has done the above comparison. By the way TurnipMan you would need a 2x phono to XLR cable if you had the NAP250 - Chord company can make them for you and can probably make any other connection you may need if you tell them what amp you end up with. Hope this helps, Craig. -- coop250 coop250's Profile: http://forums.slimdevices.com/member.php?userid=8217 View this thread: http://forums.slimdevices.com/showthread.php?t=31865 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Does Fifer do the same as me... or are you getting mixed up? I bought my NAIM-like cables from the Soundstable eBay shop (http://stores.ebay.co.uk/SoundStable). Top quality cables and unbelievably good value. Highly recommended. Make sure you specify exactly the correct cable though (for my NAP250: dual phono to 240 degree 4 pin din with locking nut)!

Ah sorry I didn't realize you were asking an amplfier specific question. Sorry I don't know. You could try checking the Naim web page for the stats I used in the Bryston example, then go forth and calculate. Covering every amplifier with a wiki page is rather a tall assignment with volunteers.

I think "Fifer" has has TP connected directly to his NAP250, at least it appears so from his sig. You could contact him for info.
