The Sony MDR-R10 tends to be very picky about amplifiers. I like the way it sounds with the Berning MicroZOTL a lot, with one exception: the bass. It’s not there. You can here where it should be, but there is no impact, and extension is not good. So, in a quest for bass out of the R10, and in light of Jan’s introductory offer on the RKV, Dusty Chalk and I put the RKV and the ZOTL on the same source, and did some comparative listening. The RKV had Mullard tubes, which Dusty feels sound the same as the stock Polamps. The ZOTL had Sylvania 12AT7WA’s (three-mica black plate) and 6SN7WGTA’s. The setup:
Sony DVP-NS500V SACD/DVD/CD player
Homegrown Audio Silver Lace interconnects
Virtual Dynamics Power 3 AC Cords
Monster HTS-2000 power conditioner
Sony MDR-R10 headphones
Grado HP-1 headphones
A couple of other headphones that merit discussion in a different post
My notes are with the R10, as my particular goal was to determine if the RKV would be a significant improvement over the ZOTL. We listened over the afternoon. Each of us would pick a track, which we would listen to for a period of time. We then switched headphones to the alternate amplifier, and listened again.
Music included:
Einsturzende Neubaten: Silence is Sexy
Sylvia Woods: Harp of Brandiswheire
The Stranglers: Meantime
Second Sight
Godhead: Power Tool Stigmata
Henry Kaiser: Those Who Know History are Doomed to Repeat it
Godhead: Nothingness
Cowboy Junkies: Open (SACD)
Yo Yo Ma, Edgar Meyer, Mark O’Connor: Appalachian Journey (SACD)
I’ll start with my bottom line (Dusty may well have reached different conclusions). The ZOTL and RKV are very similar amplifiers. Both are superb amplifiers. Neither one gets good bass response out of the Sony R10. Both are stunning with the HP-1. While I’m about to start picking at differences, in the overall scheme of things they are trivial, IMO. I wouldn’t ditch the ZOTL to buy an RKV. I wouldn’t ditch the RKV to buy a ZOTL. The ZOTL fits my personal preferences slightly better, but that may be simply because I’m used to it, while the RKV is more novel. The differences I’m going to point out are going to read as though they are more dramatic than they actually are…that’s the nature of this sort of review. I won’t reproduce all my notes, just those that seem to give a feel for the differences between the amps.
Reminder: the R10 does not produce bass well using either of these amps.
Track 2 on the Sylvia Woods album (In the Forest) has an interplay between harp, flute and acoustic bass. The RKV produced a better rendition of the bass, but neither was good, and with the ZOTL the bass tracked was almost missing in action. The harp seemed very detailed and well-articulated on the ZOTL. On the RKV, it sounded more artificial. Flute had excellent detail and air on the ZOTL. Good on the RKV, but less air.
The opening track to Einsturzende Neubaten has a very powerful bass presence. The RKV had better bass definition, as well as deeper bass. Hand drums went to the ZOTL, with better definition at the upper end. Drums on the ZOTL were precisely located, more so than RKV. The vocal on the ZOTL seemed to float against a black background. Clear, transparent, well defined. Vocal was also good on RKV, but did not stand out as much.
On Appalachian Waltz, the low acoustic strings were “glaring in their absence” on the ZOTL. Better on the RKV, but still missing the very bottom. RKV has very good tonality on the rest of the strings, but here the ZOTL was in its element. ZOTL had the mid to upper range of the strings dead on. Better sense of space, with strings more clearly articulated.
Second Sight, “Night Fires” has a nice introductory percussive crack. Impact was greater on the RKV, but definition was better on the ZOTL. There is both woodwind and synthesizer on the track. At times, with the RKV, I had trouble telling which was which. This was much easier with the ZOTL, which seemed to capture the fine tonal differences better.
Godhead’s Afterthoughts (Power Tool Stigmata) had some good bass that presented well on the RKV. It just wasn’t there on the ZOTL. There’s a percussion track that came across with good impact on the RKV, but hard to tell what it was. The percussion on the ZOTL had less impact, but more texture. By comparison, the RKV seemed to almost smear the detail of the percussive hits.
I could go on, but I think the general idea is there. The RKV has excellent bass, good midrange, but the very high end is rolled of. IMO a lot of spatial information is contained in the part of the spectrum that the RKV rolls off. The ZOTL had a clearer midrange and highs. Sense of space was better with the ZOTL, and imaging was clearer. The ZOTL seemed to be a faster amp, and was able to get at some fine detail that did not come through on the RKV. Important caveat repeat: I was using the R10, which is just about unequaled in its ability to retrieve fine detail and create a sense of space, IMO. Some of the differences I’m reporting simply won’t be there with other headphones.
So can the R10 produce bass at all? Yep. As an afterthought, at the end of the afternoon, I plugged the R10 into the Grado HPA-1…and all the bass was there. Everything at the low end that had been plaguing the ZOTL and RKV was present and accounted for with the HPA-1. Not the ultimate solution, though, since both the RKV and ZOTL are better than the HPA-1 in the midrange and highs. The Melos SHA-1 also produces better bass than either the ZOTL or RKV, but again, loses out in the mids to both, and in the highs to the ZOTL. Neither of these amps were part of the day's comparison, though.
I’d love to biamp the R10 with the HPA-1 on the bottom and ZOTL on top. Since that’s not about to happen, the search for the right amp for the R10 is going to have to continue…
