I do find the Ortofon 2M Red on the slightly warm side of neutral, but just very slightly, to my ears. There is no reason the Emo CD player would not sound neutral. That leaves the XSP-1 the prime suspect. As ADTG mentioned, you may have some EQ on, in this case it is not EQ but the high and low frequency trim circuitry. To be 100% sure it is not affected transparency, do the following:
1. Press the "Direct" button. See section 4, on page 8 in the user manual, it says:
2. Set the main line outputs to "Full Range". See section 9 on page 11 of the user manual:
Anthem STR preamp, power amp, integrated amps for sure will sound good with you speakers, but your XSP-1 and XPA-2 should also sound good with those speakers. I have Marantz, Parasound, Bryston, NAD, Outlaw, Anthem, and other amps, they all sound good. So if I tell you, like many others will, that Bryston amps sound better than Anthem, and McIntosh, Passlab, Krell, Bel Canto, Boulder amps sound better than Bryston and McIntosh etc. etc., then what are you going to buy?
For example: in one review on the MCA 525, the reviewer said:
I bet he felt those other amps sounded better than the Anthem because they were more expensive, and I would bet my money 2 to 1 he would not have passed a properly conducted blind test.
The thing is, for people who boasted how the amps they own sounded fantastic, phenomenal, authoritative, incredible or whatever, chances are really good that in a double (or even single) blind, level matched comparison listening with you Emotiva amps, they will not be able tell a difference. The fact is, your speakers, your room acoustic conditions, and your media sources and media players that determine the sound quality.
Now, do I prefer the Anthem MCA 325 or the STR integrated, or the STR preamp+STR power amp over your Emotiva amps, surely I do, but it won't be for better sound quality.
