Classe SSP 600 for preamp? only 2 channels

A young person here, well that’s a switch! Welcome.

Yes, the SSP-600 is a pre/pro.

As to the rest of your post, since you mention FLAC, I assume you are interested in digital audio file playback and, since you mention HDMI and the SSP-600, I assume you are further interested in somehow combining multichannel capability with such playback.

If I am correct in these impressions, the first thing to realize is that multichannel digital audio file playback is something that’s really on the bleeding edge. Didn’t the SSP-600 come on the market in 2005? Sitting here in October 2013 and thinking about the world of computer audio, anything that came out in 2005 strikes me as being almost prehistoric. Look ahead, not behind.

Also, even though the SSP-600 doesn’t have it, I think you may be getting needlessly hung up on HDMI. Read the Computer Audiophile review of the exaSound e28 Multichannel USB DAC. One of the things to notice is that here we have a bleeding edge component specifically designed for multichannel digital audio file playback, and guess what it doesn’t have? It doesn’t have any HDMI port, in or out.

My advice is first forget about the SSP-600 and, second, don’t limit your thinking to HDMI.

Disclaimer: On the other hand, I’m sure no expert. The vast majority of the people on this forum who are into digital audio files are into the 2 channel variety, not the multichannel variety. Most of the old geezers here (of which yours truly is one) have had enough trouble figuring out how to play 2 channel digital files through a good stereo system that we’ve not risked the mental breakdown that would probably come with trying to figure out how to play multichannel digital files through a good surround sound system! Around here, when someone talks multichannel, they are likely talking about physical SACDs or DVDs, not FLAC files.

Hi Grant. An older amp may not have all the same types of audio inputs to match all the various types of audio outputs on a new digital pre/pro; however, any amp regardless of age should have RCA type analog audio inputs that you can connect to the RCA type analog audio outputs on the digital pre/pro. Of course, if the amp is only a 2-channnel amp then with multichannel pre/pros such as those you mention you would only be using two of the eight available RCA analog audio outs on the pre/pro.

As for the brands you mention (Nuforce and Emotiva), I have no personal experience with either but both are reputable and have plenty of fans. NAD is another brand with a good reputation for value. The Emotiva XMC-1 ($2000) looks like it will have substantially more features than the Nuforce AVP-18 ($1100); however, be aware that Emotiva has been talking about bringing the XMC-1 to market for quite some time now (with major design changes along the way) so who knows how long you may have to wait for it. On the other hand, a concern I would have about the AVP-18 is that nowhere does Nuforce indicate what DAC chip it uses. This makes me suspicious as to its quality. Also, a noteworthy feature advantage of the Emotiva over the Nuforce is that the Emotiva will have streaming audio capability whereas the Nuforce appears not to. Furthermore, the AVP-18 has a single USB port which is intended for firmware upgrades, not audio. In contrast, the XMC-1 has three USB ports designed with audio in mind, including support for digital audio file formats (FLAC, WAV, AAC, and MP3) which the Nuforce appears to lack. Of course, how important these differences are will be influenced by what other equipment you might be using.

When you ask “will I be losing any quality or limiting my options if I go with these choices” (referring to the AVP-18 or the XMC-1), that’s impossible to answer without knowing more about exactly what kinds of source material (audio CD, SACD, DVD, digital audio files) you want to accommodate, which components you already have and plan to continue to use, which components you plan to buy, and your budget.
